How is Wattage Calculated?

Calculating Wattage
The formula for calculating wattage is:

W (joules per second) = V (joules per coulomb) x A (coulombs per second) where W is watts, V is volts, and A is amperes of current.

In practical terms, wattage is the power produced or used per second. For example, a 40-watt light bulb uses 40 joules per second. The wattage of the light bulb is the product of the voltage at which it operates and the rate of the current flowing through it.
