Question

5 cells, each of emf 0.2V and internal resistance 1 ohm are connected to an external circuit of resistance of 10 ohm . Find the current through
external circuit?​

Answer 1

Answer:

Since the five batteries and their internal resistances are connected in series to one another, the net emf will be nE and the internal resistance is nr.

Current through external resistance

i=

nr+R

nE

=

5×0.2+4

5×2

=2A
