Click on the flashcard to see the answer

What is a transformer?

A transformer is an electrical device that transfers electrical energy between two or more circuits through electromagnetic induction.

What are the two main components of a transformer?

The two main components of a transformer are the core and the windings.

Explain how electromagnetic induction is used in transformers.

In transformers, electromagnetic induction occurs when a changing current in one coil induces a voltage in another coil placed close to it.

What is the purpose of insulation in transformer windings?

Insulation in transformer windings prevents electrical short circuits and maintains safety and efficiency.

Why is the core of a transformer laminated?

The core of a transformer is laminated to reduce eddy current losses.
