Primary coil refers to the coil to which alternating voltage is supplied. It's usually connected to the AC supply
hope this helps
Ответ:
A). Primary coil
Explanation:
As we know that in an ideal transformer the flux linked with primary coil and secondary coil for each turn must be same
so we can say that
so as per faraday's law we can say that two EMF is given as
now we have
so we can say that
for step down transformer the output voltage is less than the input transformer
so we will have
so turns will be more in
A) Primary coil
