**Voltage** (also called **electric potential difference**) is the amount of **electric potential energy** between two points in a circuit, **per unit charge**.
### Simple Definition:
> **Voltage is the push or pressure that makes electric charges move in a circuit.**
### Units:
* The unit of voltage is the **volt (V)**.
* 1 volt = 1 joule of energy per coulomb of charge.
### Formula:
$$
V = \frac{W}{Q}
$$
Where:
* $V$ = voltage (in volts)
* $W$ = work done or energy (in joules)
* $Q$ = charge (in coulombs)
### Example:
If a battery provides **2 joules** of energy to move **1 coulomb** of charge, the voltage of the battery is:
$$
V = \frac{2}{1} = 2 \text{ volts}
$$
