- If three cells of 2 volt each are connected in series to make a battery, then the total potential difference between terminals of the battery will be 6V.
- (i) Given: p.d. = 2V, Charge moved = 1C
We know that,
p.d. = work done/charge movedWork done = p.d. x charge moved = 2 x 1
Work done = 2 joules
(ii) Given: p.d. = 6V, Charge moved = 1C
Work done = p.d. x charge moved
= 6 x 1
Work done = 6 joule ( 1ST CLICK ON REPLY THEN VEIW ANS TO GET IT CORRECTLY)

Potential Difference of a Battery
The potential difference of a battery is the difference in electric potential between its positive and negative terminals. In other words, it is the voltage that the battery can provide to a circuit.
Calculation of Potential Difference
When three 2V cells are connected in series, their voltages add up to give a total voltage of:
V = 2V + 2V + 2V = 6V
Therefore, the potential difference at the terminal of the battery is 6V.
Electric Energy Gained by 1 Coulomb
The electric energy gained by 1 coulomb of charge on passing through an electric circuit is given by the formula:
E = VQ
where E is the electric energy gained (in joules), V is the potential difference (in volts), and Q is the charge (in coulombs) that passes through the circuit.
Electric Energy Gained by 1 Coulomb in One Cell
In one cell, the potential difference is 2V. Therefore, the electric energy gained by 1 coulomb of charge on passing through one cell is:
E = VQ = 2V x 1C = 2J
Electric Energy Gained by 1 Coulomb in Three Cells
When three cells are connected in series, the potential difference becomes 6V. Therefore, the electric energy gained by 1 coulomb of charge on passing through all three cells is:
E = VQ = 6V x 1C = 6J
Explanation
When a charge passes through an electric circuit, it gains electric energy equal to the product of the potential difference and the charge. In one cell, the potential difference is 2V, so a charge of 1 coulomb gains 2 joules of energy. When three cells are connected in series, the potential difference becomes 6V, so a charge of 1 coulomb gains 6 joules of energy.
