Can the voltage drop across the inductor...

Can the voltage drop across the inductor or capacitro in a series LCR circuit be greater than the applied voltage of the ac souce?
Justify your answer.

Text Solution

Verified by Experts


(ii) Yes, the voltage drop across inductor or capacitor in a series LCR circuit can be greater than the applied voltage. This is because these voltages are not in phae and hence, can not be added like ordinary numbers.
