transformer Quiz Practice Quiz | transformer

To change the voltage of an AC power supply. — Transformers are designed to step up or step down AC voltage levels.

Laminated steel. — Laminated steel reduces eddy current losses and improves efficiency.

Input power equals output power. — In an ideal transformer, power in equals power out (no losses).

10:1 — Turns ratio is primary turns to secondary turns, therefore 100:10 = 10:1

AC only — Transformers work based on electromagnetic induction, which requires a changing magnetic field produced by AC.
