Q: What is the relationship between the primary and secondary voltages in an ideal transformer?

They are directly proportional to the number of turns in their respective coils. — Voltage is directly proportional to the number of turns (V1/V2 = N1/N2).

Q: If a transformer has 100 turns in the primary coil and 500 turns in the secondary coil, what is the voltage transformation ratio?

1:5 — Transformation ratio = N1:N2 = 100:500 which simplifies to 1:5.

Q: In an ideal transformer, what is the relationship between the primary and secondary currents?

They are inversely proportional to the number of turns in their respective coils. — Current is inversely proportional to the number of turns (I1/I2 = N2/N1).

Q: If the primary voltage is 120V and the secondary voltage is 24V, and the primary coil has 200 turns, how many turns does the secondary coil have?

40 turns — Using V1/V2 = N1/N2, then N2 = (V2/V1)*N1 = (24/120)*200 = 40 turns.

Q: Which of the following statements best describes the principle behind transformer operation?

Mutual induction between the primary and secondary coils. — Transformers work via mutual inductance created by a changing magnetic flux.
