In a series RLC circuit, the phase difference between the current in the circuit and the voltage across the capacitor is?

A)

0â°

B)

90â°

C)

180â°

D)

360â°

Correct Answer : Option (B) : 90Â°

Explanation : In a series RLC circuit, voltage across capacitor lags the current in the circuit by 90⁰ so, the phase difference between the voltage across the capacitor and the current in the circuit is 90⁰.
