Question

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

• A. the current and the $PD$ across the resistance lead the $PD$ across the inductance
• B. the current and the $P D$ 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 lags behind the $PD$ across the inductance by an angle $\pi / 2$ but the current in resistance leads the $PD$ across the inductance hv $\pi / 2$

Answer 1

Answer: (B)

Here inductance and resistance are connected in series. We know that in case of resistance, both current and potential difference are in the same phase. In inductor, voltage leads current by $\pi / 2$.
