Vs/Vp = Ns/Np
This apply in transformer.
But I have read the following statement :
' Uasally , voltage ratio is larger than the turns ratio. This is because not all field lines from primary coil cut the secondary coil.'
Why? Is that mean some field lines 'go' to surroundings?![Roll Eyes :rolleyes: :rolleyes:](data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7)
