An alternating voltage and the current causing it to flow should rise and fall in value equally and reverse direction at the same instant. When this happens, the two waves are said to be in phase and the power factor is unity (1.0). However, various inductive effects, such as idle running induction motors or transformers, can lower the power factor.
