Question

Ebonite is a good conductor of Electricity.
State whether the above statement is True or False.
A. True
B. False

Answer 1

Hint: Metals are good conductors of electricity because of the presence of free electrons whereas free electrons are not present in not present in non metals due to which they are unable to allow flow of current through them. Electricity or current flow is basically flow of free charges or electrons in a single direction.

Complete answer:
Ebonite is made up of special vulcanized rubber. Ebonite is blackish brown in color and firm, formed by mixing and heating sulfur and rubber together.Hence, ebonite is not a metal and does not have free electrons to carry current, that’s why ebonite is not a good conductor of electricity or we can say ebonite is an insulator. Therefore, the given statement is ‘False’.

Hence, the correct answer is option (B).

Additional information: But if ebonite rod is rubbed with fur, ebonite rod and the fur get oppositely charged as the ebonite rod gets negatively charged and fur gets positive. On rubbing movement of electrons takes place from fur to the ebonite rod.

Note: Remember that most of the metals are good conductors of electricity and nonmetals are generally insulators with some exceptions such as graphite (allotrope of carbon). Metals have free electrons into their atoms to carry current.
