A storage battery is connected to a charger for charging with a voltage of 12.5 V. The internal resistance of the storage battery is 1 Ω. When the charging current is 0.5 A, the emf of the storage battery is
Why this question ? Tip––––:Internal resistance of battery means that it has small resistance associated with it, and in such problems we always try to apply the ohm's law while travelling between the two points. |
