An autotransformer is equipped with a 50% tap, a 65% tap, and an 80% tap. Which of the following statements is true concerning a load connected to the 50% tap?

Correct Answer: Option C — The load is receiving one half of line voltage and drawing two times line current.

Autotransformers connected to lower percentage taps reduce output voltage while maintaining power conservation. A 50% tap delivers half the line voltage, and due to transformer winding current transformation properties, the connected load draws twice the line current.
