A Watt is a measure of power not voltage.

Voltage X Amps = Watts (in a DC circuit)

If you have a 55 watt light bulb for a car and you are looking for the amperage:

55W/13.8v = 3.99Amps (a typical alternator charging voltage is 13.8v)

One Megawatt = 1,000,000 watts. Watts = Volts x Amps or voltage x current. Hence if you know the voltage then Amps = 1,000,000 watts / Volts.


The formula you are looking for is I = W/E. Amps = Watts/Volts.



There are zero watts in 700 volts.


There is no direct relationship between watts and volts. Watts = volts x current in amps.


Volts does not determine watts. You do not have enough information.


Depends on how many Volts: Watts = Volts X Amps


You need to have the amperage to determine how many volts you get out of 20 watts.


Amps * Volts = Watts 1 Amp * 12 Volts = 12 Watts.


There are zero volts in 250 watts. To answer this question an amperage or resistance must be given. Watts = Volts x Amps. Volts = Watts/Amps.


Watts and Volts are two distinct types of measurement.



12 volts 1 amp is 12 watts. 12 volts 2 amps are 24 watts. 12 volts 10 amps are 120 watts.


4500 watts is zero volts. To obtain a voltage from watts it has to be divided by an amperage.


Watts are not rated in amps. Watts are the product of amps times volts.


To find the watts you have to multiply the volts by the amps. If there are no amps, there are no watts either.


Amps, volts and watts are interrelated, but you need to do a little math. Amps * Volts = Watts


Watts and volts are different measures for different things. Watts = Volts x Ampers. This would be closest to an answer.


There are zero watts in 90 volts. Watts is the product of amps times volts. To answer this question an amperage must be given.


Watts = Volts * Amps Therefore: 70 Watts / 13.8 Volts = 5.07 Amps


Your premise is not complete : The conversion of Watts to Volts is governed by the equation Volts = Watts/Amps For example 100 watts/10 amps = 10 volts


Five volts is zero watts. Watts are the product of amps times volts. Find the amperage of the load and them multiply it by the 5 volts and that will give you your answer.


Amps, volts and watts are interrelated, but you need to do a little math. Amps * Volts = Watts


Watts are the product of amps times volts. Therefore 175 watts is zero volts. Without an amperage the voltage cannot be calculated. E = W/I, Volts = Watts/Amps.
