select the correct answer. why does a transformer require ac rather than dc? a. so that the magnetic field can be intensified b. so that the energy will be able to be transferred from one coil to another c. so that there will be enough voltage for transformation d. so that there will be a change in the magnetic field required for induction
Answer
Answer:
D. so that there will be a change in the magnetic field required for induction
