Chapter 37, Problem 43A

Why does a transformer require alternating voltage?

To determine

The reason of requiring alternating voltage by a transformer.

Explanation of Solution

Introduction:

The transformer is a device that is used to transfer electrical energy from one place to another place. It works on electromagnetic induction.

Electromagnetic induction is the process of producing electromotive force with the help of a changing magnetic field. Thus, the alternating voltage is required in the transformer.

Conclusion:

The transformers work on the alternating voltages.
