Auto Transformer Quiz

What is the principle of an auto transformer?

• To use a single winding with a tap to provide different voltage levels

• To use a battery to provide different voltage levels

• To use a single winding without a tap to provide different voltage levels

• To use multiple windings to provide different voltage levels

How is an auto transformer constructed?

• Using multiple windings with at least four terminals

• Using two windings with at least three terminals

• Using a single winding with only two terminals

• Using a single winding with at least three terminals

Explain the working of an auto transformer.

• An auto transformer works by sharing a common winding between the primary and secondary circuits.

• An auto transformer works by using separate windings for the primary and secondary circuits.

• An auto transformer works by completely isolating the primary and secondary circuits.

• An auto transformer works by reversing the direction of current flow between the primary and secondary circuits.

What are the advantages of using an auto transformer?

• Higher cost, lower efficiency, and larger size

• No cost savings, lower efficiency, and same size

• Less reliable, more expensive, and larger in size

• Efficiency, cost-effectiveness, and smaller size

Describe the principle of an auto transformer in simple words.
