NEET Physics Phasor Diagrams MCQ Question with Solution

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

Option A

Using the phasor sum of voltages, V = √(V_R² + V_C²). Given V_R = 12V and V = 20V, V_C = √(20² - 12²) = 16V.
