secondary winding

A student observes a voltage change on a meter connected to the secondary winding.

Definition

Noun: 1. A coil in which an electrical current is induced by a changing current in a separate, magnetically linked primary coil: This is the specific component within a transformer or induction device. It is the output coil where voltage is stepped up or down relative to the input (primary winding).

Usage
  • The term is used specifically in the context of electrical engineering, physics, and electronics to describe the output side of a transformer or an induction coil.
  • It is often contrasted directly with the .
Examples
  • Noun:
    • The voltage across the secondary winding was measured to be 12 volts.
    • To increase the voltage, the secondary winding must have more turns than the primary winding.
    • A fault in the secondary winding caused the transformer to fail.
Advanced Usage
  • "Open-circuit secondary winding": A secondary winding that is not connected to a load, resulting in no current flow in the secondary circuit.
    • Testing with an open-circuit secondary winding allows you to measure the transformer's core losses.
  • "Short-circuited secondary winding": A secondary winding whose terminals are connected with very low resistance, causing very high current to flow.
    • A short-circuited secondary winding can cause excessive heating and damage the transformer.
Variants and Related Words
  • Secondary coil: A direct synonym.
  • Secondary: Often used as a shorthand in technical contexts (e.g., "the secondary voltage").
  • Primary winding (n): The input coil that carries the current which creates the magnetic field to induce a current in the secondary winding.
  • Transformer (n): A device containing both a primary and a secondary winding used to change AC voltage levels.
Synonyms
  • Secondary coil
  • Output winding (in the context of a power supply transformer)
Related Phrases
  • Coupled to the primary winding: Describes the magnetic linkage between the two coils.
    • The efficiency depends on how well the secondary winding is coupled to the primary winding.
  • Turns ratio: The ratio of the number of turns in the secondary winding to the number in the primary winding, which determines the voltage transformation.
    • The turns ratio between the secondary winding and the primary winding is 10:1.
