Question:
Describe an activity to show that thermoplastic is a poor conductor of electricity.
Answer:
We will design a circuit to see that thermoplastics are poor conductors of electricity.
We need a bulb, some wires, a battery, a piece of metal, and a plastic pipe. Set up the circuit first with the metal and then with
the plastic pipe (as shown in the figure).
After you switch on the current you will observe that the bulb glows in the former case. In the latter case, the bulb does not
glow. Hence, a plastic pipe (which is a thermoplastic) is shown to be a poor conductor of electricity.
