sähköpotentiaalieroihin

Sähköpotentiaalieroihin, commonly referred to as voltage, is a fundamental concept in electricity. It represents the difference in electric potential energy per unit charge between two points in an electric field. Imagine it as the "pressure" that drives electric current. This difference can be created by various sources, such as batteries, generators, or even static electricity.

When there is a difference in electric potential between two points, and a conductive path connects them, electric charges will flow from the point of higher potential to the point of lower potential. This flow of charge is what we call electric current. The magnitude of the potential difference directly influences the strength of the electric field and, consequently, the amount of current that can flow through a given resistance.

The standard unit for measuring electric potential difference is the volt (V), named after the Italian physicist Alessandro Volta. One volt is defined as one joule of energy per coulomb of charge. Therefore, a 1-volt potential difference means that one joule of work is done when one coulomb of charge moves between the two points. Understanding sähköpotentiaalieroihin is crucial for analyzing and designing electrical circuits and systems.
