Question

100 cells each of emf 5v and internal resistance 1ohm are to be arranged so as to produce maximum current

Answer 1

Total resistance = 1 + 1/100 = 1.01

Emf =5×100 = 500v

I = 500 / 1.01 = 50000/101 = 495 Ampere

Answer 2

Answer:2 rows will give maximum current

Explanation:

As current is inversely proportional to resistance lesser the resistance/no.of rows higher the current.
