A) 16.11 amp
B) 1.611 amp
C) 0.1611 amp
D) 2.6 amp
Correct Answer: B
Solution :
Here two cells are in series. Therefore total emf = 2E. Total resistance = R + 2r \ \[i=\frac{2E}{R+2r}=\frac{2\times 1.45}{1.5+2\times 0.15}=\frac{2.9}{1.8}=\frac{29}{18}=1.611\,amp\]You need to login to perform this action.
