Question

Define Power? Write a numerical expression to calculate it. What is its unit?​

Answer 1

Answer:

Power is the rate at which work is done. P=Wt. The SI unit for power is the watt (W), where 1 watt equals 1 joule/second (1 W=1 J/s). Because work is energy transfer, power is also the rate at which energy is expended. A 60-W light bulb, for example, expends 60 J of energy per second.

Power/SI units

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.
