## How do you calculate turns on a secondary coil?

If you want a 220 VAC in, 12V out stepdown transformer, that’s a **18.33:1 transformation ratio, so 18.33 turns on the primary for every turn on the secondary.**

## How do I calculate the number of turns in the primary coil of a transformer?

The arrangement in transformers is similar. Remember: Emf is **induced if a conductor is in a changing magnetic field. The larger the number of turns on the coil, the greater the flux linkage and therefore the greater the induced emf.**
