Which statement is true about watts?

Explanation:
Watts measure electrical power—the rate at which energy is used or transferred. Power in a circuit is P = V × I, so one watt equals one volt times one ampere. This shows why watts describe how much work is done per second by a device. Watts are not units of resistance, current, or charge; resistance is in ohms, current in amperes, and charge in coulombs. For example, a 60-watt device at 120 volts draws 0.5 amperes (P = V × I, so I = P/V = 60/120 = 0.5 A), illustrating how power relates to voltage and current.
