How do you light up a 120 volt bulb using a battery?
The principle behind those glowing orbs throughout your house is one of the most simplistic of science and circuitry. If you provide a source of energy to an able filament it will glow. Whether your source is the AC current running through your home or DC current provided by a battery, it will still yield the same result.
What will happen if use a 12v 400ma instead of 12v 500ma?
i am not sure, BUT according to the answer in this post:
Can_you_use_a_9V_600mA_adapter_on_a_9V_400ma_scanner
you need an adaptor of 9v and AT LEAST 500mA (assuming that the appliance draws 500mA)
How do you convert 120 volt to 240volt in your home for baseboard heat?
You are mixing Amps. and Watts. One is a factor of the other.
Are You Asking About The Watts Or Voltage ? Most Baseboard Heaters Are 220 Volts. So Here Is The Way To Connect A 220 Volt. You Will Need A 2 Pole Circuit Breaket That Will Fit Your Panel. The Breaker Will Need To Be Of The Correct Amperage To Handle The Amperage Of The Heater. You Will Need 10 or 12 Guage Wire Again Depending On Amperage. If Over 20 Amps I Recommend You Use 10 Guage. The Amperage Should Be On The Heater. In The Connection End Of The Heater You Will Find ( most likely ) a Green Wire ( Put Your Raw Copper Ground Wire Here. A Red Or Black Put Either Of The Other Here. Also Use The Last Wire You Have To The Final Wire On The Heater. Also There Is A Diagram On The Plate On The Heater. In The Breaker Box. Be Sure To Turn Off The Main Circuit Breaker !! Then Test To Make Sure Your Have +++ Connect One Of The Insulated Wires To The Breaker, Then The Other Also Goes On The Breaker.On The Other Connection, You Will Have Two Connections On A 2 Pole Breaker, Connect The Copper Wire To The Ground Bar== Where You Find The Other Bare Wires Connected. Be Sure To Do This Correct. If You Have Any Doubt It Is Important You Get It Correct Or You Could Burn Your House Down. Also Where You Buy The Wire And Breaker They Can Help Bunches Too.
What type of power supply is needed to power the Mitsubishi LT-70 turntable?
The Mitsubishi LT-70 turntable requires a standard AC power supply rated at 110-120V and 60Hz. It is important to ensure that the power supply meets these specifications to avoid damaging the equipment.
Can you plug 110 115 or 120 volt appliances into a 220 or 240 volt outlet?
NO! Check the rating on the device and if it says 120V only don't ever dare plug into 240V. Depending on the appliance the results will either be lots of sparks, large flashes or other undesirable side effects.
Another engineer's opinion
That answer above is for USA, Canada and other countries which use the 60Hz electrical service standard, for appliances which were designed to run only on that voltage and nothing higher.
If this question is asking about using 110V to 120V appliances plugged into sockets elsewhere in the world which use the 50Hz 230 to 240V electrical service standard - such as Europe, Australia and many other countries - then the answer is not necessarily NO.
Providing you use the correct type of plug adapter to suit the sockets in each country you visit, if the appliance was designed to run on 110V to 240V services, then the answer is YES.
There are many personal electrical and electronic appliances which were designed to run on voltages within a wide range such as 110 to 240 volts! Just a few examples are: electric razors, hair dryers, battery chargers for digital cameras, mp3 players, etc.
IMPORTANT SAFETY NOTE
Such multi-voltage small appliances should never be used on the 220 to 240 volt outlets in USA or Canada or other countries which use the 60Hz electrical service standard.
Such 220 to 240V outlets are intended for use only by large appliances, such as water heaters, clothes washing machines and dryers, cooking ranges, etc. Such 220 to 240V outlets are quite different in size to 110 to 120V outlets anyway and no adapters should ever be used to try to use those kinds of portable small appliances on 220 to 240V 60Hz.
It may be illegal to do so in some countries or states because:

Why do some houses have hard-wired electrical appliances?
If a range or garbage disposal is to be considered an "appurtenance", they can be hardwired.
It's about the mortgage company wanting to make certain that if the price of the range is a part of the original loan, they want that range to be there if/when they have to foreclose. If the range was an appurtenance and someone removes it, the mortgage company MAY have legal rights.
OTHERWISE,
It's a good idea to put a plug on the range and an outlet on the wall.
Will 240v heater work with 220v output?
Yes, a 240v heater will work with a 220v output. The slight difference in voltage should not significantly affect the heater's performance. However, it is always recommended to check the manufacturer's specifications to ensure compatibility.
Can a 230 volt bulb be used on a 120 volt circuit How does this impact wattage of the bulb?
Yes, a 230V bulb can be used on a 120V circuit, but the power output of the bulb will be approximately one quarter. (Half the voltage and half the current) Note, however, that since the bulb will be cooler, the resistance will be slightly less, so power will be somewhat higher than expected, but estimated figure is still one quarter.
Is it cheaper to run 240 volt?
NO, if you have motors that are 'convertable' -110 or 220/240, the higher voltage is more economical.
<<>>
It costs the same regardless of whether the voltage is 120 or 240 volts. The bonus of using a higher voltage is on the installation wiring costs. At a higher voltage the current of the device is lower. This lower amperage permits a smaller size wire to be used. This only really becomes a cost saving factor in larger equipment. In small power tools the higher voltage range will allow you to double the distance from the supply source to the place where the power tool is needed.
Depending on the device you might be able to just get a socket converter plug, or you might need a voltage converter.
If you look on the device where the electric wire connects(or the power brick that plugs into the wall), there should be a label on it that says something along the lines of(I took this right off my laptops power brick):
Input: 100-240V ~ 1.7A 50-60Hz
Output: 18.5V - 3.5
For this case you can ignore the output listing, we are more interested in the fact that it says 100-240V input. This means that it will work with pretty much any wall outlet in the world as long as you get a socket converter to make it fit. These are pretty cheap, you can most likely get them online or at a Radioshack, hardware store, pharmacy, or somewhere with travel equipment.
If the label reads more like this you will need a voltage converter
Input: 220-240V ~ 1.7A 50-60Hz
Output: 18.5V - 3.5
Because this one says 220-240V it won't be able to suck enough voltage out of a regular socket here in the US without a voltage converter to make it possible. I don't know if you could get these at a Radioshack or a travel store, but you can definitely find them on the internet.
The answer to this question depends entirely on which electrical system you are asking about: if it is a vehicle, the voltage could be 6 volts, 12 volts, 24 volts or even higher, such as the 600 to 1200 volts systems used to power the motors of some electric trains.
For information about voltages used for household electrical services in different countries, please see the answer to the Related Question shown below.
Can you run a 110V plug off a 220V plug?
yes, you would have to replace the single poll breaker with a 2 poll of the same trip rating. I use the word carefully often as a reminder, the circuit breaker panel is hot. If you have the luxury of turning off the main breaker, do so. It also assumed you have room for a 2 pole breaker.
Tools you will need; Flat head and/or Philips screwdriver, test light or meter, red electrical tape and wire cutters/strippers.
# With the cover carefully removed, locate the existing single poll circuit in your panel. # shut breaker off, verify with test light or meter. # Remove black wire from breaker and carefully trace back to where the wire comes into the panel. This will help you locate the paired white wire .
# Carefully remove the white wire from the neutral buss. Note: Leave the green ground wire where it is. All circuits must be grounded regardless of voltage!
# Using the red electrical (trace) tape, run a few turns of tape over the white insulation jacket to signify line 2 or another hot wire. White always represent neutral, red represents hot as does black. Note: You should repeat the trace tape step at the other end of this wire for safety.
# Neatly and carefully move new red trace wire to breaker location and pair with black. # Carefully remove existing breaker by prying the breaker up from opposite side of the screws, towards the direction of the screws.
# Carefully stab down new 2 pole breaker by first installing the foot (below the screws) of the breaker in the shoe or tab. Then carefully push the other end down over the buss bars. Note: the breaker must be in the off position. you'll get zapped other wise.
# install black wire in top screw and red trace wire in bottom screw, or match any existing 2 pole breakers in your panel. Tighten, but do not over tighten screws.
# Close up the panel flip the breaker as long as the other side is buttoned up and good luck.
Calculate per unit cost in terms of kilowatt hour for electricity?
To calculate the per unit cost of electricity in terms of kilowatt-hour, divide the total cost of electricity by the total number of kilowatt-hours consumed during a specific time period. This will give you the cost per kilowatt-hour.
Can you step down a 220v to a 110v without a transformer?
It is not possible to step down voltage from 220V to 110V without using a transformer or other voltage conversion device. Transformers are specifically designed to change voltage levels while maintaining power flow. Attempting to step down voltage without a transformer can risk damaging electrical devices or causing a safety hazard.
Can you convert a 120 volt Yamaha clavinova to 240 volts?
No, it is not recommended to convert a Yamaha Clavinova from 120 volts to 240 volts. This could damage the instrument and void any warranty it may have. It is best to purchase a Yamaha Clavinova that is already rated for 240 volts if needed.
What are some examples of appliances that use 115 volt?
Some examples of appliances that use 115 volts include lamps, radios, televisions, fans, and refrigerators. These appliances are designed to operate on the standard voltage supply found in most residential homes in the United States.
How do you change 110 volts to 240 volts?
You need to change the circuit breaker and sometimes the wiring itself. For example, if you have a 120 volt circuit with a black wire as the hot and the white as a neutral you would take the white wire off the neutral bar of the circuit breaker panel and put it on one leg of a 240 volt breaker. The receptacle would have to be changed as well. The white wire should be re colored to black or red.
Can you use a 120v cord that will fit a 240v socket the appliance is 240 and the cord is thick?
120v and 240v cords usually have different end configurations and will not plug into the different recepticles. However, if you changed the plug end, and the cord has the proper size rating, then yes, you could use the same cord. But, it also depends on the cord too. Most 120v cords only have three wires in them. One "hot one "neutral" and one "ground" wire. A 240v cord would have FOUR wires, two "hot" wires, one neutral wire, and one ground wire. Therefore, if you changed the voltage from 120v to 240 using a 3 wire cord, you'd not have a ground wire and that could be VERY dangerous.
Note that occasionally a 240v device (e.g. some motors) will only need three wires (red,black,green, no neutral) and can be wired with a 120v cord if the cord is rated for 240v.
What is the difference in 130v and 120 volt light bulb?
Not a lot. The rating is to denote the voltage the bulb is designed for. The higher rating just says it will handle voltage that high so you have a bit more flexibility if your voltage fluctuates.
Can you use a 12 volt power pack on a 9 volt keybord?
It is not recommended to use a 12 volt power pack on a 9 volt keyboard as it may damage the keyboard due to the higher voltage. It is important to match the voltage requirements of the device to the power source to prevent any issues.
No, unplugging an appliance completely cuts off its power supply and will not consume any electricity. Turning off the breaker only stops electricity flow to the appliance but there may still be some minimal energy loss due to standby power or other factors. Unplugging is more effective in reducing electricity consumption.
Could a 1650 watt outdoor electric grill be plugged into a regular household outlet?
No, a 1650 watt outdoor electric grill typically requires a 20-amp circuit, which is more power than a regular household outlet can provide. To safely use this grill, you may need to have a dedicated circuit installed by a licensed electrician.
Can a 24 volt Black and Decker battery be used on a 18 volt Black and Decker portable vacumn?
No, it is not recommended to use a 24 volt battery on an 18 volt device. Using a higher voltage battery can damage the device and may pose a safety hazard. Stick to the recommended voltage for the device to ensure proper functionality and safety.
Can you plug a 240 volt appliance into 110 volt?
No, there are two reasons, usually the 240v plug is different and will not fit into a standard 120v outlet. Second, it needs another 120v leg, that is, the 240v uses two
120v wires for the power it needs. So if you did get it to plug in and it did run, it would
not be running at the power it needed to run, so there is a chance of damage to the appliance.
What should be done is have an electrician install the correct outlet for it, this way you don't take a chance on damaging the unit and also the unit is safe to run.
What if you change the plug or get it to work, you might not be using the ground or
the neutral might be switched with the ground, in this case, you could create a unsafe condition and put family at risk.

The pin configuration of the 240 volt receptacle is different from a 120 volt pin configuration. This is a safety factor to prevent the wrong voltage being applied to the wrong devices.
Can you use a 32V 15A fuse if the appliance calls for a 125V 15A fuse?
No, you should not use a 32V 15A fuse in an appliance that requires a 125V 15A fuse. The voltage rating of the fuse is important for safety, and using a lower voltage fuse can result in the fuse not providing adequate protection and potentially causing a safety hazard. Always use the recommended fuse rating for your appliance.
