Potensiaalieron, also known as potential difference or voltage, is a fundamental concept in physics and electrical engineering that describes the difference in electric potential between two points in an electric field. It is measured in volts (V) and represents the work done per unit charge when moving a charge between those points. Potential difference is essential for understanding how electrical circuits function, as it drives the flow of electric current through conductors.

In a circuit, potential difference is generated by sources such as batteries or generators, which maintain a constant voltage between their terminals. The presence of a potential difference allows charges to move, creating an electric current. Ohm’s Law, formulated by Georg Simon Ohm, relates potential difference (V), current (I), and resistance (R) in a conductor through the equation V = I × R. This principle is foundational in analyzing and designing electrical systems.

Potential difference can be measured using instruments like voltmeters, which are connected in parallel to the components across which the voltage is to be determined. In alternating current (AC) systems, potential difference varies sinusoidally over time, while in direct current (DC) systems, it remains constant. Understanding potential difference is crucial for applications ranging from simple electronic devices to complex power grids, as it governs energy transfer and the operation of electrical components.

In summary, potential difference is a key concept that explains how electrical energy is utilized in various systems, enabling the transfer of power and the functioning of electrical devices. Its proper management is vital in ensuring efficient and safe electrical operations.
