In the figure shown, q is in coulomb and t in second. At time ( t =1 ~s ) (a) ( V _ a - V _ b =4 ~V ) (b) ( V _ b - V _ c =1 ~V ) (c) ( V _ c - V _ d =16 ~V ) (d) ( V _ a - V _ d =20 ~V )

Question

Quantrex Academy · Accepted Answer

Correct answer: C. (a), (b) and (c) are correct

( aligned & q=2 t^2 & i= d q d t =4 t & d i d t =4 A / s ~s & At t=1 s, q=2 C, i=4 A & and d i d t =4 A / s & V_a-V_b=L d i d t =1 4=4 V & V_b-V_c= q C = 2 2 =1 V & V_C-V_d=i r=4 4=16 V & V_a-V_d is summation of above three i.e. 21 V . aligned )
