How many turns does the secondary winding of a 2:1 step-up transformer have?
- Less than primary.
- More than primary.
- Less turns but with thicker wire.
Explanation from PART66Online
In a step-up transformer the secondary voltage is higher than the primary, and voltage is proportional to the number of turns. A 2:1 step-up therefore has twice as many turns on the secondary as the primary, so the secondary has more turns than the primary.

Si perchè tu hai un trasformatore che essendo 2:1 dimezza il voltaggio (es. entrano 220V ne escono 110V). Quindi saranno meno avvolgimenti del primario
