Question

define power and the its units​

Answer 1

Explanation:

In physics, power is the amount of energy transferred or converted per unit time. In the International System of Units, the unit of power is the watt, equal to one joule per second. In older works, power is sometimes called activity. Power is a scalar quantity.

SI unit: watt (W)

In SI base units: kg⋅m2⋅s−3

Derivations from other quantities: P = E/t; P = F·v; P = V·I; P = τ·ω

Answer 2

Explanation:

Power of a body is defined as the rate of doing work by the body. ... unit of power is joule per second that is nothing but watt (W).

Electricity is measured in Watts and kilowatts.
