An inductor and a resistor are connected in series with an ac source. In this circuit.

Options

A. the current and the PD across the resistance lead the PD across the inductance
B. the current and the PD across the resistance lag behind the PD across the inductance by an angle `(pi)//(2)`.
C. the current and the PD across the resistance lag behind the PD across the inductance by an angle `(pi)`.
D. the PD across the resistance lag behind the PD across the inductance by an angle `(pi)//(2)` but the current in resistance leads the PD across the inductance by `(pi)//(2)`.

Answer

B

Explanation

Here inductance and resistance are connected in sereis. We know that in case of resistane, both current and potential difference are in the same phases, in inductor, voltage leads current by `(pi)/(2)`.
