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
Options:
Answer:
C
Solution:
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.
