    Sir at 13:52, there is an error,
    While discharging, EMF > V
    (24V > 23.8V)
    While Charging, EMF < V
    (6V < 7.8V)
    You have placed the yellow boxes in the opposite directions.
    If you reverse the direction of boxes, then the example would be correct.

    • @FriendsPhysics

      In non ideal case the resistance of wire is never zero whereas due to very small resistance a large current flows in short circuit and heat produced is proportional to square x of current
