Tappings of a transformer are provided
Webprimary and secondary windings are capacitively coupled primary and secondary windings are inductively coupled primary and secondary windings are conductively coupled none of the above ⇒ In a transformer the resistance between its primary and secondary should be zero 1 Ohm 1000 Ohm infinity WebTransformer loading means you are closing the secondary circuit of the transformer. So when the secondary winding is connected to the load then current starts flowing through it which generates it's own mmf and hence it's own flux .
