Question

If five identical cells each of emf 4v, internal resistance 1 ohm are connected in series

across external resistance 5 ohm, calculate equivalent emf of combination, equivalent

internal resistance and main current in the circuit.​

Answer 1

Answer:

ANSWER

E

eff

=1.5×5

= 7.5 V

r

eff

=0.2×5

=1Ω

for maximum current flow load resistance =0Ω

⇒E

eff

=Ir

eff

⇒I=
