Consider the circuit diagram shown.Now, match the given columns and select the correct option from the codes given below

As 3  Ω and 7  Ω are in series across 6 v and in series potential divides in proportion to resistance.So VA −VD=R × XR +S = 3 ×  63+7  =1810  =  1.8  VHence (i) → (q)Similarly, VA −VB=P × VP +Q = 2 ×  62+4  =  2VVA −VB−VA −VD= VD −VB=2−1.8=0.2  VHence (ii) → (r)Energy stored in the capacitor will be zero if VB = VDi.e., PQ  =  RS  ⇒  2Q =37 or  Q=143 ΩSo (iii) → (s)Hence, [i-q], [ii-r], [iii-s] and [iv-p]
