Question

In a series LCR circuit at resonance, the voltage across the inductor is 100 V and across the capacitor is 100 V. The voltage across the resistor is:

• A. 0 V
• B. 100 V
• C. 200 V
• D. 141 V

Hint:

At resonance, circuit impedance is purely resistive.

Answer 1

The Correct Option is B

At resonance, inductive and capacitive voltages are equal and opposite, so they cancel. The applied voltage appears entirely across the resistor.
