What is the force of electrical "pressure" called?

The term that represents the force of electrical "pressure" is voltage. Voltage can be understood as the potential difference between two points in an electrical circuit and is what drives the flow of electric current. It is measured in volts and indicates how much work can be done by the current that flows when there is a circuit connection.

In electrical systems, voltage is essential because it provides the energy necessary to move electrons through conductors, thereby allowing electrical devices to function. The higher the voltage, the greater the potential energy available to motivate the current.

Current refers to the flow of electrons, and power is the rate at which electrical energy is used or transferred. Resistance is a measure of how much a material opposes the flow of current. Each of these concepts relates to voltage, but they represent different aspects of electrical circuits. Understanding voltage is crucial for comprehending how electrical systems operate and how to troubleshoot potential issues.
