In an RLC series circuit at resonance, the voltages across the resistor and the inductor are 30 V and 40 V respectively. Determine the voltage across the capacitor.
50V
30V
70V
40V
Correct answer is D
At resonance, the inductive reactance is equal to the capacitive reactance. This means that the voltage across the inductor is also equal to the voltage across the capacitor.
Therefore, the voltage across the capacitor is 40 V.
