JEE Main 2022 — Alternating Current Question with Solution
JEE Main 2022 (24 Jun Shift 2)
Question
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

Step-by-step explanation
The reactance of a circuit containing a capacitor and an inductor is given by . An AC circuit has zero reactance at resonance, i.e., when, . So, first statement is true.
The power consumption in an AC circuit is zero when circuit contains only inductance or capacitance since average power consumed in a cycle is zero for inductance or capacitance. So, second statement is false.
