Question

A storage battery is connected to a charger for charging with a voltage of 12.5 volte The internal resistance of the storage battery is 1Ω. when the charging current is 0.5 A, the storage battery is

Options

A.13 volts
B.12.5 volts
C.12 volts
D.11.5 volts

Solution

V = ε + i(r) ⇒ 12.5 = ε + (1) ⇒ ε  = 12 V
(As the battery is a storage battery it is getting charged)
