G5C01G5C

What causes a voltage to appear across the secondary winding of a transformer when an AC voltage source is connected across its primary winding?

Direct answer summary (2023-2027 NCVEC pool)

The official correct answer for G5C01 is Mutual inductance.

The key fact is Mutual inductance. Match that fact to the exact condition in the question; the other choices describe a different rule, band, component, or operating situation.
