What is the main advantage of using an autotransformer?
Step 1: Understand what an autotransformer is. It is a type of transformer that has only one winding that acts as both the primary and secondary winding.
Step 2: Learn that autotransformers are used to change voltage levels in electrical systems.
Step 3: Recognize that the main advantage of autotransformers is their efficiency. They use less energy compared to conventional transformers.
Step 4: Note that autotransformers are cost-effective because they require less material to build, making them cheaper.
Step 5: Observe that autotransformers are smaller in size, which makes them easier to install and use in tight spaces.
