Answer 1

1) A source of electricity such as cell, battery, power supply etc helps to maintain a potential difference across the conductor.

2) If 1 J of work is required to move a charge of 1 C from one point to another point, then it is said that the potential difference between the two points is 1 V.

3) The energy given to each Coulomb of charge is equal to the amount of work required to move it.

Potential difference= Work done/charge
Therefore, Work done= Potential difference x charge

where charge= 1C
Potential difference= 6V
Work done= 6x1 = 6J
Therefore, 6J of energy is given to each Coulomb of charge passing through a battery of 6V
