Voltage is the electric potential difference between two points in a circuit.

It represents the amount of energy per unit charge needed to move an electric charge from one point to another.

It is denoted by the symbol V and measured in volts (V).

Mathematically, voltage is defined as:

V = W/Q

where:

V= voltage (in volts, V)

W = work done or energy (in joules, J)

Q = electric charge (in coulombs, C)

In simple terms:
Voltage is like the “pressure” that pushes electric charges through a conductor.
A higher voltage means more energy is available to move charges through a circuit.

Example:
A 9-volt battery provides enough electric potential to push current through a small electronic device such as a radio or a remote control.
