Given below are two statements:
Statement I : An AC circuit undergoes electrical resonance if it contains either a capacitor or an inductor.
Statement II: An AC circuit containing a pure capacitor or a pure inductor consumes high power due to its non-zero power factor.
In the light of above statements, choose the correct answer from the options given below:
Statement I : An AC circuit undergoes electrical resonance if it contains either a capacitor or an inductor.
Statement II: An AC circuit containing a pure capacitor or a pure inductor consumes high power due to its non-zero power factor.
In the light of above statements, choose the correct answer from the options given below:
View answer and explanation
Correct option: C
Both Statement I and Statement II are false
Option C is correct because both statements about AC circuits and resonance are false. Statement I is incorrect as resonance requires both inductor and capacitor. Statement II is incorrect as pure capacitor or inductor circuits have a power factor of zero, hence consume no power.
