sekundaarmähisena

Sekundaarmähisena, a term derived from Estonian, directly translates to "secondary coil" in English. It refers to the coil of wire in a transformer that receives electrical energy through electromagnetic induction from a primary coil. The voltage and current in the secondary coil are determined by the ratio of turns between the primary and secondary coils, as well as the voltage and current supplied to the primary coil.

Transformers utilize the principle of electromagnetic induction, where a changing magnetic field produced by the primary coil induces a voltage in the secondary coil. This phenomenon is governed by Faraday's law of induction. The number of turns in the secondary winding dictates whether the transformer is a step-up transformer (increasing voltage) or a step-down transformer (decreasing voltage).

In practical applications, secondary coils are fundamental components in power distribution systems, electronic devices, and charging adapters. They enable the conversion of electrical energy from one voltage level to another, making it suitable for various uses. The design and construction of the secondary coil, including the wire gauge and insulation, are critical for efficient and safe operation. Its interaction with the primary coil's magnetic flux is the core mechanism by which transformers function.
