What is the role of a conductor in an electrical circuit?

The primary role of a conductor in an electrical circuit is to carry electrical current from the power source to the various components within the circuit. Conductors are materials, typically metals like copper or aluminum, that have low resistance, allowing electric charge to flow easily through them. This flow of current is essential for powering devices and completing the circuit, enabling the functioning of various electrical components such as resistors, capacitors, and other loads.

Conductors ensure that electricity generated by a power source reaches its destination effectively. By providing a pathway for current to travel, they facilitate the efficient operation of the entire electrical system. This role is fundamental and is why conductors are characterized by their ability to conduct electricity, distinguishing them from insulators, which serve the purpose of preventing current from escaping where unwanted.
