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 D — The load is receiving one half of line voltage and drawing one half of line current.

An autotransformer functions as a voltage divider. Tapping at 50% reduces the output voltage to one-half of the line voltage. Per Ohm's Law, if the load impedance remains constant, the current drawn is directly proportional to the voltage, resulting in one-half of the line current being drawn by the load.
