A transformer needs an alternating current that will create a changing magnetic fiel a changing magnetic field also induces a changing voltage in acoil this is the basis of how a transformer works this inducesan alternating current Ac in the circuit connected to thesecondary coil
tasniahh:
It induces an ac voltage in the secondary coil. That means an ac current is always produced in the secondary coil when the primary coil is an ac current, right?So why is the sentence wrong?
hmm
