Physics for IGCSE & O level - Magnets And Currents (Section 12 - No. 2)
In a step-down transformer, the number of turns in the primary coil is:
Less than the secondary coil.
More than the secondary coil.
Equal to the secondary coil.
Unrelated to the secondary coil.
Förklaring
Step-down transformers reduce voltage, which requires more turns on the primary side.
