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

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 by $\pi /2$

the current and the PD across the resistance lag behind the PD across the inductance by an angle $\pi /2$

the current and the PD across the resistance lead the PD across the inductance
