Question

Select Correct Statement about the Auto Transformer?


1.One Winding Transformer

2.Poor Voltage Regulation

3.Low Efficiency

4.All of the above​

Answer 1

Option 1 is correct

Explanation:

Auto transformers reduce the use of copper by using common winding for primary and secondary wounds. That is why they are known as one winding transformers.

Due to the usage of common wiring there is less loss of copper and more efficiency is provided by single winding transformers as compared to double winding transformers.

Auto transformer also have good voltage regulation because there is less voltage loss due to resistance in multiple winding.
