This is a modern take on inductive circuits. The capacitance and resistance are not present in the circuit, The Circuit Contains an inductor and voltage source. so you need to build the circuit so that it has an inductance and an electric field. Then after, Find the required phase difference. In case of purely capacitive circuits, the current of the circuit leads the voltage by π2π2. And in case of purely resistive circuits, there is no phase change i.e. both the voltage and current have the same phase angle.
