Question

explain an activity to show thermosetting plastics are bad conductor of electricity??
no spamming please

Answer 1

because they contain mixed type of polymer which will allow the electricity to pass through it.

Answer 2

To show this take an activity to show this:
To create the circuit we require bulb, copper wires, a battery, a piece of metal, and a plastic pipe.Set up the circuit with the metal switch on the current, the bulb glows. Next set up the circuit with pipe switch on the current the bulb does not glow.
From the experiment we conclude that plastic pipe (thermoplastic) cannot allow the current through pass it hence it is a poor conductor of electricity.
