NEET Physics Phasor Diagrams MCQ Question
Type: MCQ-numerical-Medium-Class 12
A 50 Hz a.c. source of 20 volts is connected across R and C as shown in figure. The voltage across R is 12 volts. The voltage across C is:
A
8V
B
16V
C
10V
Correct Answer
Option A
Detailed Explanation
Using the phasor sum of voltages, V = √(V_R² + V_C²). Given V_R = 12V and V = 20V, V_C = √(20² - 12²) = 16V.
