What unit is used to express electrical power?

Explanation:
Power is the rate at which electrical energy is transferred or work is done. In circuits, it equals voltage times current (P = V × I). The unit for power is the watt, defined as one joule of energy transferred per second. So a device using energy at 60 joules every second is consuming 60 watts of power. The joule is an energy unit, while the ampere measures current and the volt measures potential difference, which is why electrical devices are expressed in watts (or kilowatts for larger amounts).
