In power loss in a capacitor in A.C circuit is:
Correct answer: D. <P>= zero
- A. P > V°l°
- B. <P>= V°I° sinθl°
- C. <P>= V°I° Cos θl
- D. <P>= zero
Explanation
In purely inductive or purely capacitive circuit, power loss is zero.

About AC Through Resistor, Capacitor and Inductor
Alternating current through a resistor, capacitor and inductor involves phase relationships between voltage and current, reactance, impedance and energy transfer. A resistor keeps voltage and current in phase, while a capacitor and inductor produce opposite phase shifts, a distinction used in circuit diagrams and numerical calculations.
