A watt is defined as: W=1V*1A=1J/sec=1Nm/sec
It depends on how many Amps (current) are applied to the voltage. Watt = Volts x Amps. e.g. 12 volts @ 5 amps = 60 watts
Watt volts is not an electrical term. Watts are the product of amps times volts.
Multiply the volts by the amps to find the watts.
Amps, volts and watts are interrelated, but you need to do a little math. Amps * Volts = Watts
Zero volts equal one watt. Watts is the product of amps times volts. Without an amperage the voltage can not be calculated. The time constant has nothing to do with the equation.
The formula you are looking for is I = W/E. Amps = Watts/Volts.
To calculate the amperage of a 40-watt bulb, you need to use the formula: Amps = Watts / Volts. If the bulb operates at 120 volts (standard for US households), the amperage will be 0.33 amps (40 watts / 120 volts).
It depends on how many Amps (current) are applied to the voltage. Watt = Volts x Amps. e.g. 12 volts @ 5 amps = 60 watts
At 120 volts it will pull 4.166 amps. At 240 volts it will pull 2.08 amps.
P=EI. MEANS POWER EQUALS VOLTAGE TIME AMPERAGE .9 X 3.7 = 3.33 WATTS. 3.33 WATTS FOR ONE HOUR AT 3.7 volts
The formula you are looking for is I = W/E.
Watts = Volts x Amps So you need to know the current. This is only for resistive load.
