Transformers type

I. Step up transformer

Step up transformer increase the given voltage and decrease the current. Its primary winding consists on thick wire and less number of turns but in secondary side thin wire and more number of turn’s w.r.t primary side.

II. Step down transformer

Step down transformer decrease the given voltage and increase the current. Its primary winding consists on thin wire and more number of turns but in secondary side thick wire and less then the number of turn’s w.r.t primary side.
