Yes, sort of. At least for DC, that's correct, since P = I x V (power = current x voltage). In the case of AC, the correct formula is:
P = I x V x (power factor)
In many practical situations, the power factor is close to 1, and can therefore be ignored.

How are watts determined?
The watt is a measurement of power. In electrical circuit, to determined watts there is a formula volts x amps = watts
How many volts in a watt?
It depends on how many Amps (current) are applied to the voltage. Watt = Volts x Amps. e.g. 12 volts @ 5 amps = 60 watts
How many milliamps in 48.8 watts?
Milli amps is a measure of current whilst watt is a measure of power. The missing element is voltage as the formula is:- Power = Voltage * Amps ie power in Watts is the product of Volts (in Volts) times Amps (in Amps)
How many volts in a 500 watt work lamp?
This can be easily calculated with the following formula: Power = Volts * Amps To re-arrange to answer you question: amps = power / volts amps = 500 / 120 = 4.166 amps. Or here is an online calculator: http://www.sengpielaudio.com/calculator-ohm.htm
Does amps times voltage equal watthours?
Amps times volts = watts Watts measures the rate of power usage. watts times hours = watt hours Watt hours is a measure of the amount of power used.
What is the formula for finding out how many amps is required to achieve the full 100 watt output from a 9 volt bulb?
The formula is volts times amps equals watts, or watts divided by volts equals amps.
What kind of amps does a 65 watt light take?
amps equals watts divided by volts.
How are amps different from watts and volts?
Amps is an electric current unit and watt is an electric power unit.
How many amps does a 1000 watt 120v ballast use?
Max amps would be 1000 divided by 120.
How many volts it takes to cause a current of 1.95 amps to exist in a 200 watt lamp?
The formula to calculate the relationship between amps, volts and watts is Volts X Amps = Watts or Volts = Watts / Amps or Amps = Watts / Volts therefore; 200 Watts divided by 1.95 Amps is 102.5641 Volts.
How much Electricity is used by geyser?
It depends on the wattage of the unit. When that is found use the formula; Amps = Watts/Volts to find your answer.
How many amps in a 4400 watt output with 120 volts?
The formula you are looking for is I = W/E. Amps = Watts/Volts.
What fuse do you need to run a 200 watt bulb with 230V?
The formula you are looking for is Amps = Watts divided by Volts. Once you find the amperage you can decide as to the size of a fuse you should use. Remember that fusing protects the conductors of the circuit and not the load of the circuit. A #14 wire is rated at 15 amps and can legally be loaded only to 12 amps.
How many amps do you need for 580 watt?
A very basic formula is that power (watts) equals amperage times voltage. For example, if you are operating at 120 volts, 580 watts, the amperage would be 4.8 amps (580 divided by 120).
What is the service demand for two 15000 watt ranges?
Use this formula Amps = Watts/Volts.
How many watt in Milliamphere?
Multiply the volts by the amps to find the watts.
How do you work out watts for solar power?
Answer You need the Voltage and the amps it can supply then use the magic triangle formula that is Watt = Amps X Volts say 400mA 12 volt that will work out to .4X12 = 4.8 watt
