primaarikäämää

Primaarikäämää refers to the primary winding of a transformer. A transformer is an electrical device that transfers energy between two or more circuits through electromagnetic induction. It typically consists of two coils of wire, known as windings, wrapped around a common ferromagnetic core. The primary winding is the coil that receives the input electrical energy. When an alternating current flows through the primary winding, it creates a varying magnetic flux in the core. This changing magnetic flux then induces a voltage in the secondary winding, allowing the transformer to step up or step down voltage levels depending on the ratio of turns between the primary and secondary coils. The properties of the primary winding, such as the number of turns, wire gauge, and material, are crucial in determining the transformer's performance characteristics, including its impedance and power handling capabilities. The input voltage is applied across the primary winding, and its interaction with the magnetic core facilitates the energy transfer to the secondary winding.
