A) In B
B) In B and C
C) In A
D) Same for A, B and C
Correct Answer: C
Solution :
Resistance of A is greater than the resistance of combination of B and C, hence voltage drop across A will be greater than that across B or C. Also \[H=\frac{{{V}^{2}}t}{R}\] Þ \[H\propto {{V}^{2}}\] so \[{{H}_{A}}>({{H}_{B}}={{H}_{C}})\] (R = constant)
