The correct Answer is:
To solve the question, we need to analyze both the assertion and the reason provided. ### Step 1: Understand the Assertion The assertion states that the average power consumed in an AC circuit is equal to the average power consumed by the resistors in that circuit. **Explanation:** In an AC circuit, power is consumed by resistors, capacitors, and inductors. However, only resistors consume real power (average power), while capacitors and inductors do not consume real power; they only store and release energy. Therefore, the average power consumed in an AC circuit is indeed equal to the average power consumed by resistors. ### Step 2: Understand the Reason The reason states that the average power consumed by capacitors and inductors is zero. **Explanation:** In an AC circuit, capacitors and inductors do not consume average power because they alternate between storing energy and releasing it back to the circuit. The average power over a complete cycle for both capacitors and inductors is zero, as they do not dissipate energy like resistors do. ### Step 3: Conclusion Since both the assertion and the reason are true, and the reason correctly explains why the assertion is true, we can conclude that the statement is correct. ### Final Answer: Both the assertion and the reason are true, and the reason correctly explains the assertion. ---
