WebFeb 20, 2024 · The fact that source voltage and current are out of phase affects the power delivered to the circuit. It can be shown that the average power is \[P_{ave} = I_{rms}V_{rms}cos \, \phi,\] thus \(cos \, \phi\) is called the power factor, which can range from 0 to 1. Power factors near 1 are desirable when designing an efficient motor, for … WebJun 24, 2024 · When the power factor is less than 100%, the circuit is less efficient and has a higher operating cost. To calculate the power factor, apply the formula: P F = P T P A ×100 P F = P T P A × 100. where PF = power factor (percentage) PT = true power (in W) PA = apparent power (in VA) 100 = constant (to convert decimal to percent)
