In a series R-L-C circuit at resonance, the voltages across the resistor and the inductors are 30V and 40V respectively. What is the voltage across the capacitor?
A
30V
B
40V
C
50V
D
70V
Verified Correct Answer: B.
Physical Principles & Numerical Solution
AT resonance; \(X_L\) = \(X_c\)
\(\therefore\) = \(V_L\) = \(V_c\) = 40V
