Question

Is potential difference voltage?

Answer 1

Potential difference:

1. The potential difference between two points is said to be $1$ volt if work is done in transferring $1$ coulomb of charge from one point to another point is$1$Joule.
2. In other words, Potential difference is the difference in the amount of energy that charge carriers have between two points in a circuit.
3. Or potential difference is the measure of the stored energy in any form.
4. The S.I. Unit of potential difference is Volt.

Voltage:

1. Voltage is the work to be done upon a unit charge to move between two points against a static electric field.
2. Voltage is also known as electromotive force emf, electric pressure, or electric tension.
3. A voltage which is a measure of electric potential difference is the cause of electrical current to flow in a closed circuit.
4. Mathematically, Voltage = Work done (W) / Charge (Q).
5. Thus the unit of voltage is joule/coulomb.

Hence potential difference and voltage are different.
