    Question

    The coil of an electric generator is made up of ________ wire.

    1. Iron
    2. Plastic
    3. Copper
    4. Tungsten

    Hint:

    The coil of an electrical generator is made up of a conductor i.e. copper

    The correct answer is: Copper

      The coil of an electric generator is made up of copper wire.
      • The electric generators are designed in such a manner to induce emf inside them.
      • The coil wire must be a conductor.
      • The coil of an electric generator is made up of copper as it conducts the electricity.
