Questions

Tell the odd one out. Give a proper explanation.

Find the odd one out and give its explanation.

Options

  • Fuse wire

  • Bad conductor

  • Rubber gloves

  • Generator

MCQ
Odd One Out
Advertisements

Solution

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.
