Transformaatoritega, often referred to as transformers, are electrical devices that transfer electrical energy between two or more circuits through electromagnetic induction. They are essential components in modern electrical power systems, enabling the efficient transmission and distribution of electricity. The primary function of a transformer is to change voltage levels. They can step up voltage, increasing it for long-distance transmission to minimize power loss, or step down voltage for safe use in homes and industries.

The basic principle of operation for a transformer relies on Faraday's law of induction. It consists of two or more coils of wire, known as windings, wrapped around a common ferromagnetic core. When an alternating current flows through the primary winding, it creates a changing 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 winding to the number of turns in the secondary winding determines the voltage transformation ratio.

Transformers are broadly categorized into two types: step-up transformers, which increase voltage, and step-down transformers, which decrease voltage. They come in various sizes and designs, from small transformers found in electronic devices to large power transformers used in substations. Their reliability and efficiency have made them indispensable in power grids, allowing electricity to be generated at one voltage and then transmitted and distributed at different, more practical voltages.
