Transformers
The ratio of the secondary to primary voltage is equal to the ratio of the secondary to primary turns
Vs/Vp = Ns/Np
In an Ideal Transformer
Secondary Power = Primary Power
In reality, energy is lost through heat from eddy currents generated in the soft iron core from the changing flux.
NB: As Voltage is often referred to as e.m.f. the Symbol "e" or "E" is often used in engineering to refer to e.m.f.
This is the case in the video below.
After explaining how basic Transformers work, this video goes on to explain 3-Phase Transformers.
