transformer Quiz Practice Quiz | Transformer

Q: In an ideal transformer, what is the relationship between the primary and secondary voltages, considering N1 and N2 are the number of turns?

V1/V2 = N1/N2 — Voltage is directly proportional to the number of turns in an ideal transformer.

Q: What is the main function of the core in a transformer?

To increase the flux linkage between the primary and secondary windings. — The core concentrates the magnetic flux, improving efficiency by linking the windings effectively.

Q: What type of loss is minimized by using laminated core in a transformer?

Eddy current losses — Laminations reduce eddy currents, thereby decreasing core losses.

Q: What is the turns ratio of a transformer if the primary voltage is 220V and the secondary voltage is 11V, with 100 turns in the primary winding?

1:20 — Turns ratio = V1/V2 = 220/11 = 20:1, which means 1:20 is secondary to primary ratio.

Q: Which of the following is NOT a typical application of a transformer?

Conversion of AC to DC. — Transformers work with AC only; AC to DC conversion is handled by rectifiers.
