### What is Meant by the Power?

In Physics, power is defined as the amount of energy transferred per unit time. The SI unit to calculate the power is watt (W, which is equal to one joule per second. In other words, it is defined as the rate at which the work is done. Power is a scalar quantity. It always depends on the work done. The formula to calculate the power is given by

Power, P = Work / Time
