Answer:
1) The wires
2) A component e.g. light
3) A power source
Step-by-step explanation:
A power source is a basic part of a circuit because if the circuit doesn't have a power source, how will the electrons flow around? . A component is a basic part of a circuit because what's the point of having a circuit without something happening for example a light flashing or a motor turning. Finally, the wires are important because they carry the electrical charge for the component to turn on so if there is no wires there is no electrical flow being carried along
