Question

A Transformer Core Is Laminated To ________

Answer 1

Explanation:

The core is laminated to reduce these to a minimum as they interfere with the efficient transfer of energy from the primary coil to the secondary one. The eddy currents cause energy to be lost from the transformer as they heat up the core - meaning that electrical energy is being wasted as unwanted heat energy.

Answer 2

Answer:To avoid eddy currents

Explanation: Transformer cores are made up of thin sheets of metal stuck together with insulating varnish instead of a single block of metal.

This prevents formation of eddy currents to a great extent.
