What is the definition of voltage in an electrical context?

Voltage, in an electrical context, is defined as a measure of electrical pressure. It signifies the potential difference between two points in a circuit, which drives the flow of electric current. Just as water pressure pushes water through a pipe, voltage pushes electric charges through a conductor. This pressure is essential because it determines how much current will flow in a circuit for a given amount of resistance, as described by Ohm's Law (V = I * R, where V is voltage, I is current, and R is resistance).

Understanding voltage as electrical pressure is crucial for grasping the principles of electrical circuits and systems, enabling effective design, troubleshooting, and maintenance within agricultural technology and mechanical systems.
