Bulb Connected to an Electric Cell

When filament of a bulb is broken, it is called a short circuit.

The removal of plastic covering from electric wires would expose thread wires.

Choose the circuit component from the ends of which we have to remove plastic coating to make the conduction possible.

It is not necessary to remove the plastic coating at the ends of the copper wires while using them in an electric circuit. Do you agree with the statement? Justify your answer.

While connecting an electric bulb with an electric cell, we usually remove the plastic coatings at the ends of the wires used for connection. Explain the reason behind this.

The removal of plastic covering from electric wires would expose thread wires.
