voltage

Voltage is the electrical potential difference between two points, essentially describing the energy difference that drives electric current through a circuit. It can be thought of as the "push" that causes electrons to move, similar to water pressure in a hose that pushes water through the pipe. The higher the voltage, the greater the potential to do work, such as powering a device or lighting a bulb. Voltage is measured in volts (V) and is a fundamental factor in how electrical systems operate, determining how much energy is available to move charge and power electrical devices.
