Question

Differentiate step up and step down transformer.

Answer 1

Step up transformer	Step down transformer
The transformer used to change a low alternative voltage to a high alternating voltage is called a step up transformer, i.e. (Vs >Vp).	The transformer used to change a high alternating voltage to a low alternating voltage is called a step down transformer (Vs<Vp)
In a step up transformer, the number of turns in the secondary coil is more than the number of turns in the primary coil (Ns > Np)	In a step down transformer, the number of turns in the secondary coils are less than the number of turns in the primary coil (Ns < Np)
