Question

Describe an activity to show that thermoplastic is a poor conductor of electricity.

Answer 1

Plastics that deform easily on heating and can be reshaped are known as thermoplastics. Examples of thermoplastics are PVC, polythene, and PET.
Activity to show that thermoplastic is a poor conductor of electricity-

• We’ll build a circuit to demonstrate that thermoplastic is a poor conductor of electricity.
• A bulb, some cables, a battery, a piece of metal, and a plastic pipe are required.
• Two circuits are made- one for a metal and other for a plastic pipe.
• When the current is switched on, we see that the bulb glows in a circuit containing a metal,whereas the bulb does not glow in a circuit containing a plastic pipe.

This indicates that thermoplastic is a poor conductor of electricity.
