Step-by-step solution
Column-I: (a) In L-R series AC circuit: In an L-R circuit, the current lags behind the voltage due to the inductor. The phase difference is less than ( / 2 ). (b) In R-C series AC circuit: In an R-C circuit, the current leads the voltage. The phase angle is also less than ( / 2 ). (c) In L-C series AC circuit (XL > XC): Here, the reactance of the inductor (XL) is greater than that of the capacitor (XC), causing the current to lag behind the voltage by ( / 2 ). - (d) In purely resistive AC circuit: In a purely resis
