A reversible galvanic cell is connected to an external battery. If the EMF of the battery is less than EMF of the galvanic cell, current

Initially capacitor is kept connected to battery of EMF V for substantial period of time. Then suddenly the battery is removed and terminals X Y are connected to ends of a battery of EMF (V)/(2) as shown. What is the heat loss in the circuit after new battery is connected?

Rate of increment of energy in an inductor with time in series RL circuit getting charged with battery of EMF Eis best represented by:

A battery of EMF E produces currents 4 A and 3 A when connected to external resistance 1 Omega and 2 Omega respectively. The internal resistance of the battery is
