Answer Key / Explanation : (d) -

(d)

Effective value of resistance of parallel combination of  is

Similarly effective value of parallel combination of  and  resistance is given by

 

Hence, the circuit may be redrawn as shown in the adjacent figure, where total resistance across  and , . As potential across  is 48 V, hence
