Answer 1

Answer:

12.6A

Explanation:

Given, R = 0.5 ohm ; r = 0.1 ohm ; E = 1.4 volt ; n = 45

Since R>r , connecting the cells in series will give max current.

Effective emf = nE = 45(1.4) = 63V

Effective resistance = nr + R = 45(0.1) + 0.5

= 5 ohm

Current Imax = nE/(nr + R)

Imax = 63/5

Imax = 12.6 A

Hope this helps
