Electrical power is measured in which unit?

Explanation:
Electrical power is the rate at which electrical energy is transferred or used. The standard unit for power is the watt, defined by the relation P = V × I, where voltage times current gives power. In other words, one watt equals one volt driving one ampere of current (also expressed as one joule per second). The other units describe different quantities: ohm for resistance, volt for electrical potential difference, and ampere for current. So the watt is the correct unit for power.
