For charging a battery of emf E_1 , another battery of emf E_2 (E_2 gt E_1) is connected with their positive terminals connected together. Due to this , direction of current in battery with emf E_1 is revorsed . Does it mean that the emf is also reversed ? Give reason.

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?

In the figure shown, battery 1 has emf =6V and internal resistance = 1Omega. Battery 2 has emf =2V and internal resistance =3Omega. The wires have negligible resistance. What is the potential difference across the teminals of battery 2 ?

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
