two winding transformer Quiz Practice Quiz | Two…

To change the voltage level of an AC supply. — Transformers primarily change voltage levels via electromagnetic induction.

Number of secondary turns / Number of primary turns — Turns ratio is secondary turns divided by primary turns (Ns/Np).

Voltage is inversely proportional to current. — In an ideal transformer, power (V*I) remains constant so V and I are inversely proportional.

Laminated steel core — Laminated steel reduces eddy current losses and hysteresis losses.

DC to AC conversion — Two-winding transformers can't convert DC to AC directly (inverters do).
