उत्तर
Generator
Explanation:
Others restrict the flow of current while the generator produces it. This is because a generator’s primary function is to actively produce an electrical current. In contrast, the other three options (fuse wire, bad conductor, and rubber gloves) all function to restrict, break, or block the flow of electricity.
