Answer
Step 1 of 2
Introduction
An electrical device called a transformer uses electromagnetic induction t o move
electrical energy from one circuit to another. It comprises two or more insulated wire
coils, called windings, wound around a shared magnetic core made of a high-
permeability material like iron or steel, which enhances the magnetic coupling
between t he windings.
Given:
The f requency
The relative permeability of core
The current in the core
Expalantion
The primary winding connects to t he input voltage source, while the secondary
winding links to the load or the device requiring the transformed electrical energy.
The voltage in the secondary winding varies based on the t urn ratio between the
primary and secondary windings. If the secondary winding has more t urns than the
primary, it becomes a step-up transformer, increasing the voltage. Conversely, if the
secondary has fewer turns than t he primary, it becomes a step-down transformer,
reducing the voltage.
