STANDARD Physics Phase Difference MCQ Question
Type: MCQ-conceptual-Medium-Class 12
In a series ICR circuit the voltage across an inductor, capacitor and resistor are 20 V, 20 V and 40 V respectively. The phase difference between the applied voltage and the current in the circuit is
A
30°
B
45°
C
60°
D
0°
Correct Answer
Option D
Detailed Explanation
The phase difference is calculated using the formula tanϕ = (V_L - V_C) / V_R. Here, V_L = V_C, so tanϕ = 0, leading to ϕ = 0°.
