Which quantity is expressed in units of watts (W)?

The quantity that is expressed in Watts (W) is power. It is an SI unit, and can be obtained by multiplying voltage and current, or the square of voltage divided by the resistance, or the square of the current multiplied by the resistance.

Answer:

Power is expressed in units of watts (W)

Explanation:

Power is the speed or speed with which energy is consumed. It is also defined as the energy developed or consumed in a unit of time. Its unit of measure is the Watt. Since power is energy per unit of time, 1 W equals 1 joule / second.

Electrical appliances and circuits consume a certain amount of energy while receiving a supply of electricity, which they use to perform a job. Then, Watt's law states that the power consumed is directly proportional to the voltage supplied and the current flowing, where the voltage is the driving force (electrical pressure) after the flow of a current and the current is a measure of the speed at which the load passes through a determined reference point in a specified direction.
