defination:
- Ratio of Active Power (P) to Apparent Power (S).
- Cosine of the Angle Between Voltage (V) and Current (I).
- Ratio of the Resistance (R) to the Impedance (Z) of the Circuit.
significance:
- If the PF is low, the Current Increases for the same Power, which increases the Resistive Losses, therby reducing the efficiency.
