Question

Statement 1: An inductor and a resistor are connected in series in an AC circuit. In this circuit, the current and the potential difference across the resistance lag behind potential difference across the inductance by an angle π/2.

Statement 2: In an LR circuit, voltage leads the current by phase angle which depends on the value of inductance and resistance both.

Moderate
