Step up and step down transformer
Step up and step down transformer These two types of transformers .. step up and step down transformer are used to step up voltage from low value to high value according to turns ratio of primary and secondary windings. Step up transformer: This transformer has less primary winding than secondary winding so, we find that the [...]
What is Transformer and principle of work Introduction guide
What is transformer ? Every electrical network contains a lot of transformers but do you ask your self about what is transformer ? and why we use transformer ? In simple words transformer is static device (Don’t have any moving parts) which electric power in one circuit is transformed into electric power of the same [...]
