Question 182: AC fundamentals

Question

Given below are two statements :
Statement I : The reactance of an ac circuit is zero. It is possible that the circuit contains a capacitor and an inductor.
Statement II : In ac circuit, the average power delivered by the source never becomes zero.
In the light of the above statements, choose the correct answer from the options given below.

Accepted Answer

$$X = |{X_C} - {X_L}|$$
So, it can be zero if $${X_C} = {X_L}$$
And, average power in ac circuit can be zero.

Answer

Both Statement I and Statement II are true.

Answer

Both Statement I and Statement II are false.
