Question

2. Some object are bad conductor of electoicity. What
ase these Gubstance called ? Give few examples:
Is these property useful? If yes, explain how​

Answer 1

Answer:

Let’s know the difference between a good conductor and a bad conductor. Well, a bad conductor is also known as insulator.

Conductor: Material which allows the flow of current to pass through without any hinderance is known as conductor or a good conductor. Generally, all metals are conductors.

Insulator: Material which does not allows the flow to current to pass through is known as an insulator or you say a bad conductor. Non-metals are generally insulators.

Apart from these two categories, there is one more category i.e. semi-conductor.

Semiconductor materials such as Silicon (Si) and Germanium (Ge), have electrical properties somewhere in the middle, between those of a conductor and an insulator. They are neither good conductors nor insulators.

Some examples of conductors and insulators are mentioned below.

Conductors : Copper, Silver, Iron, Aluminium

Insulators : Paper, Wood, Plastic, Rubber

Answer 2

Answer:

insulators like rubber wood plastic etc...

yes this property comes in use when an electritian uses screw driver with plastic handle to repaire sockets so as to protect him from electric shock as plastic is an insulator or bad conductor of electricity
