The three components used to a light bulb to light is wire, light bulb, and battery(power supply)
Step-by-step explanation:
- The light bulb has the metal base that is connected to the end of an electrical circuit.
- Then the metal circuits are attached to the wires.
- When a light bulb is connected to the power supply, the current flows from one metal to another.
- As the current flows the filaments get heated and the bulb started to glow
