Solution:
Thermosetting fibre is not a good conductor of electricity because if we take the example of switchboards which are made of these plastics when we switch on it we don’t get any shock. Plastics are insulators which are bad conductors of electricity. So, from here we can say that thermosetting plastics are poor conductors of electricity.
The corrected statement would be, “The thermosetting plastics are bad conductors of electricity”.
