Capacitors - Technical MCQs

Q1:

What is the power factor if the apparent power of a circuit is 5 W, while the true power is 4 W?

A 0.0 W

B 0.8 W

C 1.0 W

D 1.25 W

ANS:B - 0.8 W

Real power (true power) =V * I * COS. Apparent power = V * I. Power factor = real power/apparent power. So, power factor = 4/5, = 0.8.
