sekundäärikelan
Sekundäärikela, often translated as secondary coil, is a fundamental component in inductive devices such as transformers and ignition coils. It is typically a coil of wire wound around a common magnetic core, or in proximity to a primary coil. The operation of a sekundäärikela is based on the principle of electromagnetic induction. When an alternating current flows through the primary coil, it generates a changing magnetic field. This changing magnetic field then passes through the secondary coil, inducing an electromotive force (EMF) or voltage across its terminals.
In a transformer, the ratio of the number of turns in the secondary coil to the number
In an ignition coil, specifically used in internal combustion engines, the secondary coil is designed to produce
