Hi everyone,
I read somewhere that when a coil is wound on a magnetic core it's electrical length becomes longer than it's physical length. I remember seeing this formula
L=l * sqrt Ue
Where L= Electrical length
l=actual (physical) length
Ue=Core permeability
Does anyone know if this is correct and if so what are the units used (Feet, meters)? I tried searching for it again but could not find it.
