Question

name any three sources of energy loss in a transformer​

Answer 1

Answer:

(ii) Ohmic loss due to the resistance of the windings (wires) - It can be reduced by using thick copper wires. (iii) Eddy current loss- It can be minimised by laminating and insulating the core of the transformer. (iv) Hysteresis loss - It can be minimised by using material(soft iron) which has a low hysteresis loss

Answer 2

Explanation:

The sources of energy loss in a transformer are

(i) eddy current losses due to iron core

(ii) flux leakage losses.

(iii) Copper losses due to heating up of copper wires

(iv) Hysteresis losses due to magnetisation and demagnetisation of core.
