About this video

Transformer is static device which is used to convert voltage or current up or down. Transformer is two types step up and step down. In step up voltage increase and current decrease where in step down voltage decrease and current increase. Transformer can not change frequency it can only change voltage or current.
Transformer may be so many ratings according to use. It's rating is denoted as KVA as it is no load when it's in load output will be denoted as KW.
