An autotransformer is a special type of transformer that has a. a single winding which serves as both primary and secondary. a separate primary and secondary winding. more than one primary winding. two secondary windings connected in series. b. C. d. 2. The power on the primary side of an autotransformer is less than the power on the secondary side. much greater than the power on the secondary side. exactly equal to the power on the secondary side. C. d. slightly greater than the power on the secondary side. 3. a. b. What is the secondary voltage when a source voltage of 150-V is applied across the complete winding of a center-tapped autotransformer? a. 300 V b. 150 V c. 75 V d. 225 V 4. The secondary current in a step-up autotransformer equals the turns ratio. cannot exceed the winding current. a. b. C. is less than the primary current. d. is not limited. 5. The apparent power rating of a 10:1 autotransformer is 450 VA. This means that the apparent power rating of the secondary is a. 45 VA b. 4500 VA C. d. 450 VA none of the above. REVIEW QUESTIONS 1.
