feszültségi

Feszültségi is a Hungarian term that translates to "voltage" in English. It refers to the electric potential difference between two points in an electric field. This potential difference is what drives electric current to flow through a conductor. Voltage is a fundamental concept in electrical engineering and physics, and it is measured in volts (V).

The concept of voltage can be understood by analogy with water pressure. Just as water pressure causes water to flow through pipes, voltage causes electric charge to flow through wires. A higher voltage means a greater electrical pressure, leading to a stronger flow of current if the resistance is constant.

Voltage can be generated in various ways, including by batteries, generators, and solar cells. In a battery, chemical reactions produce a potential difference. Generators use electromagnetic induction to create voltage, often by rotating a coil of wire within a magnetic field. Solar cells convert light energy directly into electrical energy, creating a voltage.

Understanding voltage is crucial for analyzing and designing electrical circuits. It is a key factor in determining the power an electrical device consumes or delivers. For instance, household appliances are designed to operate at specific voltage levels, typically 120V or 240V depending on the region. Incorrect voltage can lead to malfunction or damage to electrical equipment.
