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?
- 30V
-
40V
- 50V
- 70V
The correct answer is: B
Explanation
AT resonance; X\(_{L}\) = X\(_{c}\)
\(\therefore\) = V\(_{L}\) = V\(_{c}\) = 40V
