Question

Which of the following is true for an a.c. circuit?
Options
A All elements in the circuit dissipate power
B Reactive elements only are associated with apparent power
C Power is dependent on impedance
Correct Answer
D Power factor of purely resistive element is zero
Correct Answer

Option C is the correct answer.

Detailed Explanation

Real power P=VI cos(phi)=VI(R/Z) depends explicitly on impedance.

Hint

Real power P=VI cos(phi)=VI(R/Z) depends explicitly on impedance.
