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