Given below are two statements:
Statement I: When the frequency of an AC source in a series LCR circuit increases, the current in the circuit first increases, attains a maximum value and then decreases.
Statement II: In a series LCR circuit, the value of power factor at resonance is one.
In the light of given statements, choose the most appropriate answer from the options given below.

Verified by ExpertsC
When an a.c. voltage is applied in a series LCR circuit, the current is increased first, attains a maximum and then decreases.
The formula to calculate the power factor is given by
…(i)
At resonance, X L = X c , Hence,

Thus, both the statements are true.
