A circuit element when connected to an AC supply of peak voltage gives a peak current of which is in phase with the voltage. A second element when connected to the same AC supply also gives the same value of peak current which lags behind the voltage by . If and are connected in series to the same supply, what will be the rms value of the current in ampere?

The correct answer is:
As current is in phase with the applied voltage, element should be resistive with .
As current lags behind voltage by , element should be inductive with
When and are connector in series,
Impedance,
Now, peak current,
Thus, the rms value of current is
