Select the energy chain to power a flashlights light
The energy chain to power a flashlight's light typically consists of the following components:
1. Battery: The battery serves as the primary source of energy for the flashlight. It can be either disposable (such as alkaline batteries) or rechargeable (such as lithium-ion batteries).
2. Electrodes: The electrodes are metal terminals present in the battery. They allow the flow of electric current in and out of the battery.
3. Conductive wires: These wires connect the battery to the flashlight's circuitry, enabling the flow of electricity.
4. Switch: The switch controls the flow of electricity from the battery to the flashlight's light. It can be turned on or off to control the illumination.
5. Light bulb or LED: The light bulb or LED (Light Emitting Diode) is the component that produces light when electricity passes through it. In modern flashlights, LEDs are increasingly used due to their energy efficiency and longer lifespan compared to traditional incandescent bulbs.
6. Reflective housing or lens: Flashlights often have a reflective housing or lens that helps focus and direct the light emitted by the light bulb or LED.
Overall, this sequence of components in the energy chain ensures that electrical energy from the battery is converted into light energy by the light bulb or LED, allowing the flashlight to produce illumination.
