Answer Details
The main purpose of the transformer in an a.c radio set is to "step up" or "step down" the voltage of the alternating current that comes from the power outlet to a voltage level suitable for the operation of the radio. The voltage level required by the radio is typically different from the voltage level of the power outlet, and this is where the transformer comes in. It consists of two coils of wire wound around a core, and when an alternating current flows through one of the coils, it induces an alternating current in the other coil, but with a different voltage level. This allows the radio to receive the appropriate voltage for its operation. Therefore, the correct option is "step up the voltage" or "step down the voltage," depending on the specific application.
