Transformer Principles and Applications Quiz

A transformer transfers AC electrical power from one circuit to another at a constant frequency, while altering the voltage level.

A transformer works on the principle of Faraday’s Law of Electromagnetic Induction.

Magnetic Hysteresis is the phenomenon of flux density B lagging behind the magnetizing force H in a magnetic material.
