How many turns would be in the primary winding for each turn in the secondary winding?

The number of turns in the primary winding for each turn in the secondary winding is determined by the transformer's turn ratio. This ratio is usually given as a specification for the transformer.

Here are the steps to calculate it:

1. Identify the transformer's turn ratio. This is usually given as a specification for the transformer. For example, a transformer might have a turn ratio of 10:1.

2. Divide the number of turns in the primary winding by the number of turns in the secondary winding. For example, if the transformer has a turn ratio of 10:1, this means there are 10 turns in the primary winding for each turn in the secondary winding.

So, the number of turns in the primary winding for each turn in the secondary winding depends on the transformer's turn ratio.
