In the context of electrical circuits, what is meant by 'Voltage'?

Voltage refers to the force that pushes electric charges through a circuit. It is often described as the electrical potential difference between two points in a circuit, which creates the necessary pressure that drives electrical current. When there is a difference in voltage, it enables electrons to move from one point to another, facilitating the flow of electricity.

In practical terms, voltage can be thought of as the energy per unit charge provided by a source, such as a battery or electrical outlet. This force is essential for the operation of any electrical device, as it determines how much current will flow in the circuit, provided that resistance remains constant. In essence, without voltage, there would be no movement of electric charge, and appliances would not function.
