What is a Toroidal Transformer?

Toroidal Transformer Definition

A toroidal transformer is defined as a type of electrical transformer with a donut-shaped core, made from materials like laminated iron or ferrite.

Electromagnetic Induction

Toroidal transformers work by transferring power through electromagnetic induction, creating a current in the secondary winding.
