A battery is of emf E is being charged from a charger and hence current inside the cell is from anode to cathode
I=V−E/r
V=E+Ir
Therefore, when a cell is being charged the potential difference across its terminals is greater than emf of a cell. Also in charging the positive terminal is connected to anode of the cell and negative terminal to cathode.
Here, 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.
Hence, Potential difference across points A and B must be more than E, A must be at higher potential than B and In battery, current flows from positive terminal to the negative terminal

Overview:
This question is related to the charging of a battery from a charger. The battery has an electromotive force (EMF) E and an internal resistance r. The positive terminal of the battery is connected to terminal A of the charger, and the negative terminal is connected to terminal B. We need to determine the correct statements regarding the potential difference across points A and B, the potential at terminal A compared to terminal B, the direction of current flow in the battery, and whether any current flows through the battery.
Solution:
Potential difference across points A and B:
The potential difference across points A and B can be determined using Ohm's law. According to Ohm's law, the potential difference (V) across a resistor is equal to the current (I) through the resistor multiplied by its resistance (R). In this case, the resistance is the internal resistance of the battery (r). So, the potential difference across points A and B can be expressed as V = I * r.
Since the battery is being charged, current flows from the charger to the battery. Therefore, the current (I) is positive. As a result, the potential difference across points A and B must be more than the EMF of the battery (E) because the potential difference includes the voltage drop across the internal resistance.
Potential at terminal A compared to terminal B:
In a circuit, the potential decreases as we move in the direction of current flow. This means that terminal B, which is connected to the negative terminal of the battery, will be at a lower potential compared to terminal A, which is connected to the positive terminal of the battery. Therefore, terminal A must be at a higher potential than terminal B.
Direction of current flow in the battery:
In a battery, current flows from the higher potential (positive terminal) to the lower potential (negative terminal). This is because the battery acts as a source of electrical energy and pushes the charges in the circuit in the opposite direction to the electric field created by the battery. Therefore, the current flows from the positive terminal to the negative terminal of the battery.
Whether any current flows through the battery:
When the battery is being charged, current flows through the battery in the opposite direction to its normal current flow. This is because the charger applies a higher potential to the positive terminal of the battery compared to its negative terminal. Therefore, a charging current flows through the battery from the positive terminal to the negative terminal.
In summary:
- The potential difference across points A and B must be more than the EMF of the battery (E).
- Terminal A must be at a higher potential than terminal B.
- In a battery, current flows from the positive terminal to the negative terminal.
- When the battery is being charged, a charging current flows through the battery from the positive terminal to the negative terminal.
