How do I step down a step up transformer ?
by

1 Answer

Answer :

If we want to step up a transformer, we need to punch more of the secondary coil than the number of punches of the primary coil of the transformer. And in order to determine the number of these punches, we need to know the area of ​​cross section of the transformer and according to the formula, the primary and secondary of the transformer have to be taken with the required punch. Since this has already been written on our electronics site, I did not repeat it. Read the article from this link.
