Introduction

In this experiment, we will construct a basic electric generator using a DC motor and a light-emitting diode (LED). The objective is to understand how mechanical energy can be converted into electrical energy and observe the principles of electricity generation in action.

Materials Required

• DC motor
• Pulley
• Light-emitting diode (LED)
• LED holder
• Nut, bolt, and washer
• Plywood
• Wooden stands
• DIY mat
• Hot melting glue
• Pliers

 Concept of Electricity

• Definition: Electricity is energy that comes from the movement of charged particles, primarily travelling through materials known as conductors, like copper wires.
• Everyday Use: We rely on electricity to power various electronic devices, such as cars, washing machines, heaters, and many others.

Types of Electricity

• Static Electricity: This type of electricity occurs when two objects become charged through friction. For example, when a plastic pipe attracts small pieces of paper due to static charge.
• Current Electricity: This involves the flow of electric charge through a conductor. A common instance is when a light bulb is turned on, and the glowing filament indicates the flow of current. Current electricity can be further categorized into direct current (DC) and alternating current (AC).

The DC Motor and LED 

• DC Motor:. The DC motor is a crucial part of this project because it generates electricity when its shaft spins. Conversely, it can also function as a motor when we provide electricity to it. The shaft of the DC motor can be easily turned using a simple mechanical setup.
• Light-Emitting Diode (LED): An LED is used in this project to demonstrate electricity generation. When a 1.5-volt LED is connected to the motor, we can observe the production of electricity. It’s important to note that LEDs allow electricity to flow in only one direction.
• Working Principle: By connecting the DC motor and the LED in the right way, we can see how mechanical energy is converted into electrical energy. This project illustrates the basic principles of electricity generation using simple components.

Step-by-Step Instructions 

• Step 1: Creating the Wheel
  • Collect two old CDs and a piece of circular cardboard.
  • Use hot glue to attach the cardboard between the CDs, creating a sturdy wheel.
• Step 2: Setting Up the Base
  • Glue a wooden bar to a plywood base, ensuring it can rotate freely.
  • Secure a nut and bolt to the CD and wooden bar for added stability.
  • Attach a suitable rod to serve as a handle for turning the CD wheel.
• Step 3: Connecting the DC Motor and LED
  • Solder the DC motor and LED onto a small wooden block, following the demonstration in the video.
  • Use a rubber band wire as a belt to connect the CD wheel to the DC motor's shaft.
  • When you start turning the wheel, the LED will light up, indicating the generation of electricity.

Benefits of the Electric Generator Science Project
