NEET Physics AC Voltage MCQ Question
Type: MCQ-numerical-Easy-Class 12
In an AC circuit with voltages across a resistor (V_R) and a capacitor (V_C), how should the total voltage across the RC combination be calculated?
A
V_RC = V_R + V_C
B
V_RC = V_R - V_C
C
V_RC = sqrt(V_R^2 + V_C^2)
D
V_RC = V_R * V_C
Correct Answer
Option C
Detailed Explanation
In an AC circuit, the total voltage across an RC combination is the square root of the sum of the squares of the individual voltages, due to their phase difference.
