WebThe autotransformer has a single winding and sends voltage to the filament and high voltage circuit. The autotransformer, also called the variable transformer, works using alternating current, is self-inducting, and has only one wire and one core. The autotransformer selects the major or minor kVp and steps the voltage up to kilovolts. WebAutotransformer 1. Describe the construction of autotransformer? 2.
