Question

Why does one remove the plastic coating of connecting wires before making circuits?

Answer 1

Answer:

plastic is a bad conductor of electricity so it does not conduct the flow of current, hence it is required to remove the plastic coating in order to join the circuits and make current flow

plastic is used to protect the inner copper wire from external damage and magnetic fluxes

Answer 2

Answer:

We remove the plastic coating of connecting wires before making circuits because the plastic coating acts as an insulator. As insulators does not conduct electricity, we remove them. The copper wires, which conducts electricity makes joints to create a circuits.
