Secondary Coil - English Definition & Meaning

Definition

A secondary coil is the output coil in a transformer that receives energy from the primary coil via electromagnetic induction. It's where the voltage is either stepped up or stepped down. Think of it as the receiving end of an energy transfer, like a wireless charger's receiver ⚡. It converts the magnetic field back into electrical energy. The number of turns in the secondary coil determines the output voltage. It's an essential component in electrical devices, from power grids to phone chargers.

Etymology

The term 'secondary coil' consists of 'secondary' and 'coil.' 'Secondary' comes from the Latin 'secundarius,' meaning following or second in order. 'Coil' refers to a series of loops or windings of wire. The term describes the coil that receives energy after the primary coil in a transformer.
