PhysicsAlternating CurrentMHT CET

An alternating e. m. f. of 100 V (rms) is applied to a series LCR circuit. At resonance, the potential difference across the inductance and across the capacitance is 400 V each. The potential difference across the resistance will be

Answer: (A)

Solution

At resonance the equal and opposite voltages of L and C cancel, so the whole supply voltage appears across R:
