Understanding the Components and Connections of the Flashlight Circuit - JSS1 Basic technology Lesson Note
- Power Source: The batteries provide the necessary voltage to power the flashlight. They are usually connected in series to increase the total voltage output.
- Switch: The switch controls the flow of electricity in the circuit. When the switch is closed, it completes the circuit, allowing current to flow. When it is open, the circuit is broken, and the current stops, turning off the light.
- Light Source: The light source, often an LED or incandescent bulb, emits light when current flows through it. LEDs are preferred due to their energy efficiency and longer lifespan.
- **Conductors: Wires or conductive paths connect the components, allowing the current to flow through the circuit. The connections must be secure to ensure a continuous flow of electricity.
- Resistor (if applicable): Sometimes, a resistor is used to limit the current to a safe level for the light source, preventing it from burning out.
