For maximum power from battery the internal resistance of battery r is

Show that the power supplied by a battery to an external reistance is maximum when it is equal to the internal resistance of the batter. Further show that this maximum power is (e^(2))/(4r) where is the emf of the battery and r is internal reisistance.

A battery is of emf E is being charged from a charger such that positive terminal of the battery is connected to terminal A of charger and negative terminal of the battery is connected to terminal B of charger. The internal resistance of the battery is r .

Maximum power by battery and potential gradient

A battery supplies 150W and 196 W power to two resistance of 6Omega and 4Omega when they are connected separately to it. The internal resistance of the battery is:-
