Hint: Potential difference is the difference in the amount of energy that charge carriers have between two points in a circuit. Potential difference \[\left( {p.d.} \right)\] is measured in volts \[\left( V \right)\] and is also called voltage.
Complete answer:
The work required to transfer a charge from one point to another is described as potential difference. For a charge to pass between two points, there must be a potential difference in current. The potential energy difference per unit charge or voltage is another term for it. The Volt is the unit of potential difference \[\left( V \right)\].
We can also say that the amount of work required to move a unit positive charge from one point to another is described as a potential difference.
\[1{\text{ }}Joule/Coulomb{\text{ }} = {\text{ }}1{\text{ }}Volt\]
The volt is the SI unit for potential difference\[\left( V \right)\] . \[1{\text{ }}volt\] = The potential difference between two points in a current carrying conductor when \[1{\text{ }}joule\] of work is performed to transfer a charge of \[1{\text{ }}coulomb\] from one point to the other.
Note: The potential difference (which is the same as voltage) is equal to the amount of current multiplied by the resistance. A potential difference of one Volt is equal to one Joule of energy being used by one Coulomb of charge when it flows between two points in a circuit.
