Final answer:
The watt (W) is a unit of power.
Step-by-step explanation:
The watt (W) is a unit of power. It is the rate at which work is done or the rate of transfer of energy. It is defined as 1 watt = 1 joule per second (1 W = 1 J/s).
For example, households in the U.S. often have circuit breakers allowing maximum currents of 15 or 20 Amps for regular power outlets. At a voltage of 120V, this corresponds to a maximum power of 1800W or 2400W, respectively.
