What is the Power Formula?

Power is denoted by P and the power formula is as follows. P = V2 / R or P = I2 x R. Here V(Volt), R(Resistance), represents I(Current).

How Many Types of Power Are There?

There are 3 types of power. These:

  • Active Power (P): P = V.I.Cos(ϕ)
  • Reactive Power (Q) Formula: Q = V.I. Sin(ϕ)
  • Apparent Power (S) Formula: S = V.I
