The majority of homes in the world include electric circuits for lighting and power to appliances. Some provide cooking and heating through electricity.
No, it costs the same no matter what voltage is used. The cost is based on the kilo wattage used per hour. The equation that best explains this is Watts = Amps x Volts. For example if there is a device that draws 1000 watts, it is the product of the amps drawn by the voltage needed to make the...
it should work as long as the batteries are connected in series + to -what you would need to check is if the charger for the cart charges 24vor 8v if it is 8v you would need to get a 24v charger for itit would be possible to charge the batteries with a 12v charger but it would need to be hooked to...
With most pull chain fan switches, you'll need to replace the  switch, though on some models you may be able to reattach the  chain. To replace the switch, you will need to know whether it  operates the fan or light. If the switch goes to the fan, you will  need to know how many speeds the fan...
To test a GFCI outlet, push the button that says TEST on it. If the power goes off, it is working and if it doesn't go off, it is not working (Call a qualified electrician to replace it). You should test a GFCI every month.
The work or energy in Joules is the power in watts times the numberof second it runs for. So 500 watts for 150 seconds is 75,000Joules.
The best way to charge a battery from an AC source is to use a high-quality commercial battery charger that is of the correct voltage and charging profile for your battery. By "charging profile," I mean a charger that is matched to the battery's chemistry and amp-hour capacity. WARNING: Not every...

-Turn off the power -Remove the cover plate-Remove the wires-Strip the neutral and ground wires-Attach the GFCI-Attach the neutral wire-Push the wires back into the box and replace the cover.
Some GFIs have an audible alarm and buzz when they trip. Answer I have found that a GFI that has been painted over or corroded stuck will cause a buzz when it is overloaded and trying to trip. The problem is when it is painted over and seized open it cannot trip and causes a buzz. I would first...
Change the outlet and only use one hot wire and the neutral.<<>>Yes, most of the time it is converted with a step down transformer.
Answer for USA, Canada and countries running a 60 Hertz supply service.   In commercial and industrial installations it is important to have the whole building phased correctly. Usually these types of businesses are three phase. Three phase motors that have plugs on them for quick swapping in...
Depends on what caused the power to go off, could be seconds or it could be days.
The 194 bulb is ~3.8 watts, at 14 volts they draw 0.271 amps.
a power supply (eg: battery) and a load (eg: resistor) even a piece wire shorting two terminals of the power supply is a closed circuit
A new outlet (running new wire) or replacing an old one (wires already there)?Shut off the Power to that Receptical, diconnect the receptical, and reconnect the New receptical using the Wires from the one you replaced. Then turn the power back on and Test it with a Tester!
The ground wire (equipment grounding conductor) runs back to the panel then to a ground rod. If there is a ground fault in the circuit, the current will flow on the equipment grounding conductor back to ground.Electricity follows the path of least resistance. This is why a ground wire is so...
There are 72,000,000,000,000 watts in 72,000 giga watts.
A rather strange question, as most transformers are installed by trained individuals who wouldn't be using this forum for help. However, it will be necessary to refer to the manufacturer's specifications for that specific transformer in order to determine how to achieve the desired output.
Go to a construction equipment rental store (including some home improvement chains) and get a "utility line detector" (specialized metal detector) for a couple of hours. Make sure you get one that is sensitive enough to detect a line buried up to 6 feet deep. Scan the ground surface and use bricks...
Three phase voltage will transfer higher power than single phaseP1-ph = Vp x Ip cosφP3-ph = _/3 x VL X IL x cosφ= 3 x Vp x Ip cosφ
A three-phase separator is used in the oil industry to separate  oil, water and gas from a mixture.
the answer is not a lot as long as the circuit of any appliance is not damaged the ground is not in use.The ground wire is a safety it takes stray electricity away from faulty devices and into the ground.All houses and buildings should be wired with a ground wire.the ground wire is a yellow/green...
If the dryer doesn't heat, but the drum turns, check the thermal  fuse(s). The thermal fuse protects the dryer from overheating and  helps to prevent fires. If the thermal fuse is blown, it will have  to be replaced.
Check with your power company on the price per kilowatt. Multiply that price by 1 (1,000 watts is 1 kilowatt).
A:The circuitry that follows will be sitting at the input line potential.
Look on the main fuse panel, you should find a place there.
Single pole thermostats are used for 120 volt circuits. Double pole  thermostats are used for 240 volt circuits.
do not have a starter electrode; ballast circuits and high-voltage  electronic starter.
Yes. Thicker wires can handle more current. The following links have all the details.
Answer for UK and European electrical system.    Guide to connecting a new socket outlet to the power cables of a  ring main, and fixing it to the back box or pattress in the wall.  Depending upon where in the circuit you are fitting the socket you  may have one, two or three sets of...
Well unless you mistyped something 500kva is 500,000 watts. That  would be 41,666 12 volt batteries!
Through the use of a 'multiplier', i.e. a carefully-calibrated  resistor connected in series with (in the case of an analogue  instrument) the instrument's operating coil.
 An illustrated explanation of the differences between  single-conductor wires and multiconductor cables   In older homes, the electrical system is likely made up of single  conductor wires. Today, however, much of electrical wiring is done  with multiconductor cables because of their...
I'm not sure what you mean by "thicker resistance" wire? The  thicker or more diameter of a wire the less resistance it has. A  larger diameter wire would produce less heat. More resistance would  produce more heat.
On 9 December 1868,[8] the first, non-electric, gas-lit trafficlights were installed outside the Houses of Parliament in London tocontrol the traffic in Bridge Street, Great George Street andParliament Street. They were proposed by the railway engineer J. P.Knight of Nottingham, who had adapted this...
A three way switch is one of two devices that is used in operating  a load from two different positions. This type of electrical  circuit is known as three way switching. This terminology is used  in North America, in Europe and the UK this type of switching is  known as two way switching.
I'm not sure but i think its the coils of wire
It only takes 6 mA across the heart to die. 10 mA through your body will make all you muscles tighten up and you will not be able to let go.
A: assuming a power transformer the resistance of the primary will log in at approximately 15 ohm. But there are many types for many application so this rule can change.
Due to the fact that it needs to be grounded in-case there is a short in the energy flow so no one gets electrocuted.
A 60 watt lamp uses 60 watt-hours in one hour, so it uses 480 watt-hours, or 0.48 kilowatt-hours in 8 hours. This is also the same as 1.728 mega-joules. (60 joules/second (watts) * 3600 seconds/hour * 8 hours)
  In the USA the National Electrical Code prohibits the "point of attachment" of an overhead electric service to be within 36 inches of an openable window, doorway, or porch... in other words they do not want a person to be able to reach out of a building opening and be able to touch exposed...
I=amps, P=power(watts), E=volts I=P/EI=2600/208I=12.5 amps
Change either the plug or the cord. The fourth prong is another ground. It would be easier to change the cord.
A fuse link will melt and interrupt the flow of current to the appliance before it can get high enough to damage the appliance or wiring.
Depends on what it is powering. The longer the run the more voltage  drop you get. For example if you run 200 feet of copper 10 wire  you'll lose about 4 volts. There are voltage calculators you can  use. The less volts you have the more amps the wire will have.  Watts/volts=amps. 10 wire is...
Yes - but mainly because they are able to sense the moisture and stop once your clothes are dry. If your old unit is still running fine except for minor mechanical (belt, rollers, pulleys) or electrical (element) issues, fix it yourself to save some money!
1000 mA == 1 Amp. So take 0.015 x 1000 and you get 15 or 15mA
Make sure power is turned off and locked out so no one can turn it on while you are working on it. If you are not sure hire a qualified electrician
A: impressed voltage is a mechanical connection involved induced has no mechanical connection except for proximity
The whole world almost everybody has tried and saw and probably got  electrocuted but curious cat got ran over
they produce a large current of air that can affect the the way the  air feels
False. The minimum Service Drop Conductor size is a #6 Copper 75  Degree C and 90 Degree C Insulation or 60A. You would need a #4 or  better in Aluminum with the same insulation values.
Yes. The breaker can be smaller, but not larger than the circuit it is protecting. The situation you describe would normally be protected by a 20A breaker, but what you suggest is fine. You couldn't go the other direction and use a 30 A breaker because it wouldn't protect the lesser rated components...
Hire a qualified electrician to change your 240 volt receptacle to a 120 volt receptacle. Electricity is dangerous someone could get hurt or a fire started if you do not know what you are doing.
Yes you can. It involves working in the breaker box and changing out breakers. You'll also have to "re-identify" the black wire to green for your ground.If you think you can do this, post back and I'll provide details on how.Yes I Can! The fuse box has 2 30amp fuses.       At the breaker...
That's a 3 phase receptacle. Normally you can wire each phase onto  any terminal. The only thing is if there's a rotation involved in  the thing that your wiring you need to change any of the two wires  to change the rotation.
Maybe, it depends on what company you actually work at.
.183A or 183 Milliamps. Power/Watts Divided by Voltage will give  you Amperes
AC (Alternating Current)
Electric current has to flow in a closed circuit because, if it were not closed there would be no place for the current to flow.You could transfer charge, certainly, but you would not be able to sustain a current. Look at Ohm's law: voltage equals current times resistance - an open circuit is simply...
The electricity that flows in wires is called current, it is measured in amps.
The label 60 watts bulb max is referring to each individual bulb, not the total in the light fixture.
are the three switches all together in one box? Is there a 3 way  switch involved?
What about them!
Redox or oxidation-reduction reactions.
You can not change AC into DC using a transformer. A transformer changes the voltage levels. To change AC into DC, you would need a rectifier. To change that into smooth DC you need a capaciter and a voltage regulater
  == Answer ==     The existing 4 wires meaning Red, Black, White, Bare? Red and black are "hot" (using 120V from each phase of your service entrance), white is neutral, and bare is ground.   == Answer ==   Ground the bare or green wire to the electrical box then use red and black...
No. Normally they can go right against the wall unless anything in  its manual prohibits it.
The only true way to add a ground to an old metallic fixture is by  drilling a hole and installing a self threading UL Listed ground  screw through a metallic part on the inside of the light fixture.  Make sure the surface where the grounding conductor is to be  attached under the new screw is...
You can use #6 copper. It's technically rated for 55 amps but the  rules in the code book (240.4(B) allows you to use it for a 60 amp  disconnect.
In an energy saving light bulb, the electricity passes through a  gas which causes it to emit ultraviolet rays. When these rays pass  through the flourescent coating, the become visible, white light.    Actually an energy saving light bulb is simply any light bulb  that uses significantly...
Producing Microwaves for the Microwave to heat your food
Voltage is not "used" Voltage is constant.
When an electric current flows through a purely resistive load, the temperature of that load increases above that of the surroundings, and energy is lost through heat transfer. This energy loss is permanent and, in AC circuits, the rate of this loss is referred to as true power which is measured in...
A: LEDS are basically a diodes.So yes they can be strung right across the AC line. Unfortunately the reverse voltage is very low and tend to leak at hi voltage. the design should provide protection for the reverse voltage with resistance across each toequalize the leakage current otherwise it will...
Any audio signal has to contain varying sound frequencies, which are a form of ac.
DC is used in simple systems like cars which rely on a battery, and  most electronics systems like computers and radios run on DC and  require a converter if run from the mains.

Australia uses 240V, while North America uses 110V, so in order for  your appliances to work you will need to get an adapter.
It works normally. Well actually there are 380 volts across two  lines of a 3 phase AC source, so it should work normally.
No, it shouldn't. You are billed by watts usage. Volts X amps. A  corroded breaker will cause other problems and should be replaced  right away. High heat and possible fire can occur.
LA is short form for Lightning Arrestor
There are voltage stabilizers that can be installed to accomplish  this. A Google search will point you in the right direction.
