Astep-down transformer has more loops on which coil?
a. primary coil
b. secondary coil
c. neither
d. both

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

absorption lines are where light has been absorbed by the atom thus you see a dip in the spectrum whereas.

emission spectra have spikes in the spectra due to atoms releasing photons at those wavelengths.
