transzformátorokban

A transzformátorokban (Hungarian for "in transformers") refers to the operational principles and applications of transformers, electrical devices that transfer electrical energy between two or more circuits through electromagnetic induction. They are fundamental components in AC power systems and are used to increase or decrease voltage levels. This process relies on Faraday's law of induction, where a changing magnetic field in a core induces a voltage in a secondary coil.

The core of a transformer is typically made of ferromagnetic material, such as laminated iron, to concentrate the magnetic flux and minimize energy losses. Transformers consist of at least two coils of wire, the primary and secondary windings, wound around this core. When an alternating current flows through the primary winding, it creates a fluctuating magnetic field in the core. This changing magnetic field then induces an alternating voltage in the secondary winding.

The ratio of the number of turns in the primary coil to the number of turns in the secondary coil determines the voltage transformation ratio. If the secondary coil has more turns than the primary, it is a step-up transformer, increasing the voltage. Conversely, if it has fewer turns, it is a step-down transformer, decreasing the voltage. Transformers are essential for efficient long-distance power transmission, reducing voltage for safe distribution to homes and businesses, and in various electronic devices for power regulation and signal isolation. Their widespread use makes them a cornerstone of modern electrical engineering.
