### Coil Span Formula

coil_span = Commutator/Number of poles
Ycs = S/P

## Why transformers are rated in kVA ?

Copper loss of a transformer depends on current and iron loss on voltage . Hence total losses depend on Volt- Ampere and not on the power factor. That is why the rating of transformers are in kVA and not in kW.

## How to Calculate Coil Span?
