Potentsiaalierinevus

Potentsiaalierinevus, commonly known as electric potential difference or voltage, is a fundamental concept in electromagnetism. It represents the difference in electric potential between two points in an electric field. This difference is what drives electric charge to flow, creating an electric current. Imagine it like a water pressure difference in a pipe; the higher the pressure difference, the faster the water flows. Similarly, a larger potential difference across a conductor will cause a greater amount of electric charge to flow through it per unit time.

The SI unit for electric potential difference is the volt (V), named after Alessandro Volta. One volt is defined as the potential difference between two points when one joule of energy is used to move one coulomb of electric charge from one point to the other. In simpler terms, voltage is the "push" or "driving force" that makes electrons move. This force can be generated by sources like batteries, power supplies, or electric generators. Understanding potential difference is crucial for analyzing electric circuits and comprehending how electrical energy is transmitted and utilized.
