What are the three essential components of a complete circuit?

  1. Source, conductor, and switch

  2. Source, conductor, and load

  3. Source, fuse, and load

  4. Conductor, resistor, and load

The correct answer is: Source, conductor, and load

A complete electrical circuit consists of three essential components: a source, a conductor, and a load. The source provides the electrical energy, which can come from batteries, generators, or other forms of power supply. The conductor, typically made of metal wires, allows the flow of electric current from the source to the load. The load represents the device or component that consumes the electrical energy to perform work, such as lights, appliances, or motors. This combination is foundational to understanding basic circuit functionality. Without the source, there is no energy flow; without conductors, the current cannot move; and without a load, the energy cannot be utilized. Each component is crucial for the circuit to operate effectively and safely.
