Fundamentals of Transformers Quiz Practice Quiz…

Mutual induction — Transformers transfer electrical energy using mutual induction between coils.

Laminated steel — Laminated steel minimizes eddy current losses, improving efficiency.

Higher — A step-up transformer increases the voltage from primary to secondary.

Secondary turns / Primary turns — Turns ratio = Ns/Np, where Ns is secondary turns, Np is primary turns.

100% — An ideal transformer has no losses and thus 100% efficiency.
