Draw the diagram of torch and give function of each part?
In this how can we make but I know how can we make the diagram of toys and gift functions of each part

Parts of a Torch and their Functions:
1. Battery: The battery is the power source of the torch. It provides electrical energy to the circuit, allowing the torch to produce light. The battery is usually placed in the handle or body of the torch.
2. Switch: The switch is a mechanism that controls the flow of electricity in the torch. It can be a simple on/off button or a more complex switch with multiple modes (e.g., high, low, blinking). When the switch is pressed, it completes the circuit and allows the current to flow.
3. Bulb: The bulb, also known as the light source or lamp, is the component that emits light when electricity passes through it. It is typically a small, incandescent or LED (Light-Emitting Diode) bulb. The bulb is protected by a glass or plastic cover, which helps focus the light and prevent damage.
4. Reflector: The reflector is a curved surface placed behind the bulb. Its purpose is to reflect and direct the light forward, increasing the brightness and range of the torch. The reflector is usually made of shiny metal or coated with a reflective material.
5. Lens: Some torches have a lens placed in front of the bulb. The lens helps focus and concentrate the light, providing a more concentrated beam. It can also be used to adjust the beam's width or shape, allowing for spot or floodlight modes.
6. Body/Handle: The body or handle of the torch is the main structure that houses all the components. It is designed to be comfortable to hold and grip. The body may also have a textured surface or rubberized grip to prevent slipping.
7. Head: The head of the torch is the front part that contains the bulb, reflector, and lens (if applicable). It is usually detachable or rotatable, allowing for adjustments in the beam's focus or direction.
8. Strap/Holster: Some torches come with a strap or holster for easy carrying and accessibility. The strap can be worn around the wrist or attached to a belt, ensuring the torch is readily available when needed.
9. Body/Power Indicator: Certain torches have a power indicator, such as an LED light or colored button, to show the battery level or operational status. This feature helps users monitor the remaining power and avoid unexpected battery drain.
Conclusion:
A torch consists of various components working together to produce light. The battery supplies power, the switch controls the circuit, the bulb emits light, the reflector directs and enhances the light, and the lens (if present) focuses and adjusts the beam. The body and head of the torch provide structure and support, while additional features like a strap or power indicator enhance usability.
