  2. Ba-s, b-q, c-p, d-r
  3. Ca-s, b-r, c-q, d-p
  4. Da-p, b-s, c-r, d-q

Correct answer

A. a-q, b-r, c-p, d-s

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
