WebReactive power can also be obtained by the following equation. The calculation results show that it is equal to equation (24). The power factor of the RLC series circuit can also be obtained by the ratio of " active power " to " apparent power ". The calculation yields the following equation, which is equal to equations (16) and (17). WebFeb 21, 2024 · The formula for calculating apparent power is S = V x I, where V is the voltage and I is the current. Apparent power is always positive, as it represents the total power flowing through the circuit. Power factor: The power factor is the ratio of real power to apparent power in an AC circuit.
