Sekundaarikäämään

Sekundaarikäämään, often translated as secondary winding, refers to the coil in a transformer that receives its electrical energy by electromagnetic induction from the primary winding. When an alternating current flows through the primary coil, it generates a fluctuating magnetic field. This magnetic field permeates the transformer's core, typically made of a ferromagnetic material, and in turn induces a voltage in the secondary coil. The ratio of turns between the primary and secondary windings determines whether the transformer steps up or steps down the voltage. If the secondary winding has more turns than the primary, the voltage is stepped up. Conversely, if the secondary winding has fewer turns, the voltage is stepped down. The secondary winding is crucial for delivering the transformed electrical power to the load. Its construction involves insulated wire wound around the same core as the primary winding, ensuring efficient magnetic coupling. The design and material of the secondary winding are important factors in the transformer's overall performance, efficiency, and safety.
