What if you get 190 volts output from your house which last year the output voltage was 120 volts?

The voltage of 190 volts is odd on a 120 volt system. Check your meter against another one that is known to be accurate to make sure that the first meter is not giving you a wrong reading.

Can you plug in a 115 amp welder into a 110 volt outlet?
yes. 110,115,120,125 and even 130 volts are all in the same catagory. as power companies increased their output voltages through the years, 110 became 115, then 120, and so on. when buying light bulbs, look for the 130 volts on the bulbs data. not wattage, voltage. they will last far longer than 115,120 volts
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.
I have a coolant motor with 420 volts in Lathe Machine but the supply voltage will be 480 volts. Can 420 volts 50Hz coolant motor can use in 480 volts 60Hz?
No, you'll burn your lathe motor up immediately. (it might last 30 seconds before it literally smokes.) You'll need to buy and install a "buck-boost" type transformer to drop the voltage from 480 to 420V. Best to have a qualified commercial electrician wire it up if you value your lathe.
How many batteries would it take to light a 12 volt 100 watt light bulb?
12 volt batteries vary in size. You need to look at the amp hours of a battery and multiply by the voltage. So, a 100 amp hour battery at 12 volts is 1200 watt hours. 30 watt bulb will eat that up at 30 watts and hour. 1200 divided by 30 is 40 hours. Simple huh!? *Something to keep in mind is if your 30 Watt light bulb is rated 30 watts at 12 volts. If it is rated 30 watts at 24 volts, 110 volts or another voltage it will also change the length of time your battery will last.
What is the difference between 115V and 120v?
I disagree with the part about the "feud" between Edison and Westinghouse. The feud was between Edison and Tesla and their financial backers JP Morgan and Westinghouse, respectively. Nicola Tesla once worked for Thomas Edison and when he began asking questions about alternating current, Edison did not take his theories seriously and fired him. Telsa spent a few years unemployed until he met Westinghouse who believed in Tesla's theories and began backing his expiriments financially. It was after Tesla's success in proving his theories that Edison became aware of the competition and instead of joining forces, decided to hold public demonstrations as scare tactics for turning the public against the high voltage needed for alternating current. As the article states, direct current does not travel very far so a coal burning plant would be needed to create the steam needed to turn the generators for creating electric current. Tesla's alternating current was a much higher voltage which enabled it to travel greater distances without the need for as many coal burning plants. Tesla believed he could send current into the atmosphere to be drawn by appliances and vehicles for free. He also wanted to generate enough power to destroy asteroids that orbited too close to the Earth. Tesla survived Westinghouse and turned to JP Morgan for financial backing in his later years. He spent his last few years of his life waiting for a call from JP Morgan that never came. He died 2 years before the end of World War II and his notebooks have been confiscated by the US government and have never been released. The Tesla/Westinghouse tower was dismantled in 1917 during World War I and several attempts have been made to restore the property. There are ongoing efforts to preserve the grounds and make a documentary to retell his story.
How many watts is 5 amps?
600 This depends on the voltage Voltage x Amps = Watts ex. At 120 volts 5 amps WILL BE 600 watts But at 110 Volts (Some house voltage), it will be 550 watts And at 277 Volt (commercial-Industrial Voltage), it would be 1385 Watts If you know Watts (Like a 75w Incandescent Lamp) and the Voltage: Watts / Volts = Amps So 75w / 120v = 0.625a The last would be Watts / Amps = Volts 600w / 5a = 120v

What is 1N4OO1silicon diodes?
It's 1N4001 Maximum reverse voltage 50 volts, 1 amp The last digit indicates the voltage. To replace a 1N4001, you could safely use any of the diodes in that series. 1N4001 = 50 volts 1N4002 = 100 volts 1N4003 = 200 volts 1N4004 = 400 volts 1N4005 = 600 volts 1N4006 = 800 volts 1N4007 = 1000 volts The 1N4000 series diodes are rectifier diodes. They're used for converting AC voltage into DC voltage. And frankly, I can't think of a reason why I'd choose the 1N4001 when the more-versatile (as in you can use it in more places) 1N4003 is the same price.

How much voltage is 4 9 volt batteries?
> 36 volts. > Originally answered by Contributor This is a trick question correct right??? Is the question how many volts are four, 9 volt batteries or is it how many volts are in a 49 volt battery(if it exists)? Four nominally rated 9 volt batteries wired in series would yield about 36 volts while the same four wired in parallel would provide ~4 times more current or last about 4 times longer in the same circuit. The battery rating shown on the battery is a nominal voltage the actual voltage output of the battery can be higher or lower. First different technology batteries actually produce physically different output voltages. ie: a battery is made of cells and dependent on the type of chemistry the cell is made from the actual per cell output can very from 1.2 volts up. Batteries made with Lead plates surrounded in Sulfuric Acid (typical car batteries) can produce 2.0 volts per cell (measured open circuit). Lap top Batteries can be about 3.6 - 3.7 volts per cell while alkaline batteries (flashlight batteries) start out at 1.5 volts. To obtain higher voltage battery outputs the cells are wired in series and the voltages adds up. To obtain more current capacity cells are wired in parallel. These are nominal voltages the circuit drain causes the cell voltage to drop eventually the battery output is to low to power the application it is used in at which point it is considered dead. Even though there may still be some energy left in the battery. A good simple explanation of battery characteristics can be found at the first related link below. A more detailed and technical explanation can be found on Wikipedia at the second related link below.
What is the voltage of a blender?
The blender itself has no voltage. It's designed to operate best and last longest when it's plugged into an outlet that supplies a specific voltage, depending on the country where the blender is marketed. In the US, that's around 120 volts AC. If the blender will be sold in other countries, it may be designed for different voltage.

What is the difference from between the voltage from the photocells and the voltage used in the home?
Voltage coming from a single photovoltaic cell is around 0.5 volts or the equivalent of a dead AA battery from your remote. It also moves in a straight line. This is called DC or Direct Current. The power Coming out of the outlet in your house is 120 volt that is equal to 240 photovoltaic cells or solar cells. Last unlike the power coming from the cells the power from your house does NOT MOVE IN A STRAIGHT LINE it moves back and forth 60 time a second.
Can a 1650mAh battery replace a 1350mAh battery?
Provided it is of the same size and voltage output, Yes. The "mAh" refers to the time it will last "milli Amp hours".
Need help sizing a resistor to reduce voltage from 277V to 120v with a 200mw watt load at 120volts?
Start with the load of 0.2 watts. The power rule says that watts equals volts times amps, or amps equals watts divided by volts, so 0.2 watts at 120 volts means 0.00167 amps. Now, look at Kirchoff's current law, which implies that the current in a series circuit is the same at all points. This means that the current in the resistor is also 0.00167 amps. Now, look at Kirchoff's voltage law, which implies that the sum of the voltage drops in a series circuit adds up to the voltage source. This means that the voltage across the resistor is 157 volts. Last, look at Ohm's law, which says that resistance is voltage divided by current. 157 volts divided by 0.00167 amps is 94,200 ohms. The nearest standard 5% value to that is 91,000 Ohms. Before leaving, though, check the power in the resistor. It is 157 volts times 0.00167 amps, or 0.26 watts, so you need at least a half watt resistor.
