Would you like to make it the primary and merge this question into it?

exists and is an alternate of .

When you first turn on a motor it is starting from a static position and more current is required to get the motor up to speed (Starting current) than to keep it running (running current). Since watts equals amps times voltage you can see the difference in wattage is related to current. If you look at watts as work being done it is obvious that it requires more work to get the motor running than to keep it running.

How long does a watt run for?

A watt is a measure of power. It is volts multiplied by amperes, or just volt-amps to lots of electrical types. The amount of power is very easy to measure, but it can be used quickly or slowly, depending on the device "sucking up the power" from the source. A watt can last for a long, long time (as (MORE)
