Q. A battery is made by connecting 6 cells each having capacity 5 Ah at 1.5V. The battery will have capacity equal to
A) 20 Ah at 9 V
B) 30 Ah at 1.5 V
C) 5 Ah at 9 V
D) 5 Ah at 1.5 V
Explanation
(c) When cells are connected in series: emf increase but current capacity remains unchanged. The emf of 6 cells in series $= 6 \times 1.5 = 9\ V$ and current capacity $= 5A\ h$
