(A) : An inductance and a resistance are connected in series with an A.C. circuit. In this circuit the current and the potential difference across the resistance lag behind potential difference across the inductance by an angle `pi//2`.
(R): In L-R circuit voltage lags the current by phase angle which depends on the value of inductance and resistance both.
