STANDARD Physics Phase Angle in LCR Circuits MCQ Question

Type: MCQ-conceptual-Medium-Class 12

In series LCR circuit, the phase angle between supply voltage and current is

A

tanϕ = XLXCR\frac{X_L - X_C}{R}

B

tanϕ = RXLXC\frac{R}{X_L - X_C}

C

tanϕ = RXL+XC\frac{R}{X_L + X_C}

D

tanϕ = XL+XCR\frac{X_L + X_C}{R}

Correct Answer

Option A

Detailed Explanation

The phase angle ϕ in a series LCR circuit is given by tanϕ = (X_L - X_C)/R, where X_L is the inductive reactance, X_C is the capacitive reactance, and R is the resistance.
