WebHomework help starts here! Engineering Electrical Engineering 2. A load draws 10 A from a 120-V line at a power factor of 0.8 lagging. a) Draw the power triangle; b) Determine the … WebJul 5, 2024 · The power factor of an AC circuit can be defined as the ratio of the active power to the apparent power (total power), i.e., P o w e r F a c t o r = A c t i v e P o w e r A p p a r e n t P o w e r. ⇒ P F = V I cos φ V I = cos φ. Hence, the power factor of an AC circuit is the cosine of phase angle between the voltage and current.
