Wattage and voltage are two different forms of measuring electrical power.
Voltage is measure of the strength of an electrical charge.
Wattage is the measure of the consumption of that charge.
Wattage is used to measure the heat generated from the flow of electricity between two points whereas voltage measures the density of electrical charge of that flow. The wattage produced is directly proportionate to the electrical resistance of the item when voltage is applied to or travels across it. This is why a 100 watt bulb is brighter than a 50 watt bulb. By using an element with a higher resistance to an electrical charge in a 100 watt bulb than a 50 watt bulb the 100 produces a higher "glow" because the electricity cannot travel as freely across the element causing it to heat up thereby consuming a larger amount of the charge passing through it. The amount the charge dissipates from one side to the other is the wattage. Or more eloquently stated as Ohm's law: The current through a conductor between two points is directly proportional to the potential difference across the two points.

How many amps is equal to 1 kilo volt amp?
A volt-amp or VA is equivalent to watts, provided the voltage and amperage are in phase. So 1 kilo volt amp is the same as 1 kilowatt. Wattage, or power, is equal to volts times amps. So the original question is effectively nonsense. The number of amps depends on the voltage. If the voltage is 1000 volts, then there's 1 amp in 1 kilo volt amp. If the voltage is 1 volt, then there's 1000 amps. If there's 50 volts, then the amperage is 20 amps. And so on.
How do you convert 24 volt trailer lights to 12 volt?
All you have to do is change the bulbs to 12 volts and supply the trailer with a 12 volt power source. If you leave the original 24 volt bulb in the trailer they will only glow at 1/2 of their rated wattage.
Does a 120 volt light use less than a 240 volt light?
The question is "use less of what?". If they are both the same wattage the 240 V light will use 1/2 the current of a 120 V light.
How many kilowatts in 1kva?
Its a bit of a trick question. 1 watt is one volt-amp except in situations where the power factor has increased or decreased that ratio. For instance with a power factor of .8 a volt-amp is equal to .8 watts. So with a perfect power factor 1 kva (kilo-volt-amp) is equal to 1 kilowatt. But if the power factor is something other then 1 you can find it by pf*w=va.
How many watts in a Kva?
A VA is a volt-ampere, or volt-amp, and a kilo (K) is one thousand. This makes a KVA a kilovolt-ampere, or kilovolt-amp. If we have 1,000 volt-amps, and one volt times one amp is equal to one watt (W), which it is, 1,000 volt-amps is equal to 1,000 watts, or 1 KW. All that said, 1 KVA is equal to 1 KW.Sometimes in an ac system, the watts is less than the volts times the amps, and in that case the watts is equal to the volts times the amps times the power factor. The power factor is less than one. The power factor for a typical electric motor is 0.7, so then there are only 700 watts in a kVA.

What is an electric volt?
Volt is the unit of voltage.One volt is equal to 1 joule per coulomb:1 V = 1 J/C
What is electric volt?
Volt is the unit of voltage.One volt is equal to 1 joule per coulomb:1 V = 1 J/C
Can you use 220 volt light bulb on 120 volt system - I know the reverse would probably blow the bulb so wouldn't European 220 Volt do ok in 120 volt socket or would it be dimmer than it normally would?
Yes a 220 volt light bulb will run on a 120 volt circuit but at 1/4 of the wattage that the light bulb is rated at. A 100 watt light bulb on 220 would would be equal to a 25 watt light bult on 120 volt system.
Can a 208 volt hot water heater be used with 110 volt with a 20 amp fuse?
Yes, but by using 120 volts on the 208 volt element you will only be able to obtain 1/4 of the rated wattage from the element not 1/2 like it seems you should.
How many volts are in a hectovolt?
1 volt is equal to 0.01 hectovolt. Therefore, there are 100 volts in one hectovolt
How many amps does a can light use?
The answer depends entirely on the wattage of bulb used! You can find the amperage of your light by using the Power Law which states that amperage = wattage divided by voltage. Thus a 60 watt bulb on a 120 volt system would draw .5 or 1/2 an amp.

What is the basic metric measurement unit that is equal to 1 Volt Amperes?
1 volt x 1 ampere = 1 watt, a unit of power. One watt is also the same as one joule / second.
