The correct Answer is:
To solve the given problem, we need to analyze the two statements provided. ### Step 1: Analyze Statement I **Statement I:** An AC circuit undergoes electrical resonance if it contains either a capacitor or an inductor. **Explanation:** - Electrical resonance in an AC circuit occurs when the inductive reactance (XL) equals the capacitive reactance (XC). This condition is met when both a capacitor and an inductor are present in the circuit. - If the circuit contains only a capacitor or only an inductor, it cannot achieve resonance because there is no opposing reactance to balance out the other. **Conclusion for Statement I:** This statement is **false**. ### Step 2: Analyze Statement II **Statement II:** An AC circuit containing a pure capacitor or a pure inductor consumes high power due to its non-zero power factor. **Explanation:** - A pure capacitor or a pure inductor does not consume real power in an AC circuit. The power factor (PF) for a pure capacitor is 0 (leading) and for a pure inductor is also 0 (lagging). - Since the power factor is zero, the average power consumed by the circuit is also zero. Therefore, it does not consume high power. **Conclusion for Statement II:** This statement is **false**. ### Final Conclusion Both statements are false. ### Summary of the Solution: - Statement I is false because resonance requires both a capacitor and an inductor. - Statement II is false because pure capacitors and inductors have a power factor of zero, leading to zero average power consumption.
