Power usage is measured in what unit?

Explanation:
Power usage is measured in watts because a watt quantifies how much energy is used or transferred each second. In electrical terms, power equals voltage times current, so a watt is defined as one volt multiplied by one ampere. This makes watts the natural unit for electrical power. Amperes measure the rate of charge flow, volts measure electrical potential, and lumens measure light output, so they don’t directly represent power.
