Final Answer:

An autotransformer can indeed be used to both buck (reduce) or boost (increase) the supply voltage. So it is True.

Explanation:

Autotransformers are a type of electrical transformer that have a single winding with a central tap. They are used to adjust the voltage level of the supply.

Bucking. When the load is connected to a tap with fewer turns on the autotransformer winding, it reduces the output voltage compared to the input voltage. This is known as bucking, and it's useful when you need to lower the voltage for specific equipment or devices that require a lower voltage level.

Boosting.Conversely, if the load is connected to a tap with more turns, the autotransformer increases the output voltage compared to the input voltage. This is called boosting and is essential in situations where you need to raise the voltage to meet the requirements of certain devices or to compensate for voltage drops in long power transmission lines.

Autotransformers are efficient and cost-effective for voltage regulation purposes compared to conventional transformers. They find applications in various fields, such as power distribution, industrial processes, and electronic equipment where precise voltage control is necessary.
