Formula of Power As discussed, power is the rate of doing work. Therefore, it can be calculated by dividing work done by time. P = W t Where, P is the power, W is the work done and t is the time taken. We can define power as the rate of doing work, and it is the amount of energy consumed per unit of time. The formula for power is given below. The formula for power is given below. Therefore, it can be calculated by dividing work done by time.

  • We can express this as P=V*I and because V=I*R, we get P = I*I*R or P=I 2 R. In the same way P=V 2 /R. Like Ohm's law, this is summarized in a triangle like this. Power is directly linked to Ohm's by Joule's law, which says that the heat produced in resistance is proportional to the square of the current flowing through it over a given time.
