What does voltage refer to in an electric context?

Voltage in an electric context represents the electromotive force, which is the driving factor that pushes electric current through a circuit. It is essentially the potential difference between two points in an electrical field and is measured in volts. Just like water pressure pushes water through pipes, voltage creates the force needed for electric charge to flow in a circuit.

This concept is fundamental to understanding how electricity works, as a higher voltage can lead to a greater current flow, depending on the resistance within the circuit. Recognizing voltage as the force behind current flow is critical for anyone working with electrical systems, as it impacts how devices and circuits function. Knowing this helps in troubleshooting, designing, and working with electrical applications, ensuring they operate safely and effectively.
