The transformer laminations are insulated from each other by

The correct answer is: D. any of the above.

Transformer laminations are insulated from each other to prevent eddy currents from flowing between them. Eddy currents are induced currents that flow in a closed loop in a conductor when a magnetic field is applied. They can cause a loss of power in the transformer.

There are a number of ways to insulate transformer laminations. The most common methods are:

• Mica: Mica is a natural mineral that is an excellent insulator. It is often used in the form of thin
