The diagram below shows how an LED (light emitting diode) flashlight works.
SAMPLE ANSWER
The diagram illustrates the internal structure and functioning of an LED flashlight. It shows the arrangement of components and how electric current flows through the device.
The flashlight contains two batteries placed one above the other, which provide the power source. At the bottom, a metal spring holds the batteries in place and also conducts electricity. A slide switch, when moved downward, connects two metal contacts, completing the circuit. This enables the flow of electric current from the batteries through the switch and up to the LED bulb, illuminating it.
When the switch is in the ‘off’ position, the circuit is broken and the current cannot pass through, resulting in the LED remaining unlit. When the switch is in the ‘on’ position, it allows current to flow, lighting the bulb.
Overall, the diagram effectively demonstrates how a simple circuit in an LED flashlight functions to control the flow of electricity.
