Watt

A Watt is a measure of electrical power. The power through a circuit in Watts is given by the voltage * current.

Equations

 * P = U&times;I

Could also be written as Where P is Power, I is Current and U isVoltage
 * I = P&divide;U
 * U = P&divide;I

These equations is closely related to and is often used together with Ohm's Law Example

A 110 Watt bulb connected to the wall in the US (110 volts) would be drawing 1 amp(current). 110volts * 1amps = 110 watts.
