Answer 2

Components required to conduct electricity are written below-

To conduct electricity, along with copper wire and electric bulb, cell is required.

Copper wire conducts electricity or electrons that are responsible for flow of current.

Electric bulb confirms conduction of electricity is taking place.

Cell is the source of current, hence it is the most important component for electricity to generate.

Switch can be added to regulate the flow of current.
