We have video tutorials of the project and working model on various topics. You can use these project for your Science exhibition & for you practical examination. For the ease and convince of students we also provided a well prepared investigatory project PDF with most of these Models.
1. Thermoelectric Generator
Thermoelectric generator is a device which convert thermal energy in to electric energy. It is best project for science Exhibition. The total cost for making this project is somewhere between 300-400 (INR). A well prepared investigatory project pdf is also available with is Model.
Note: You have to follow some precaution while making this project. A detailed precaution is given in the description of this video on YouTube.
2. Electromagnetic Induction
The name of this project is Wireless Power Transmitter. It works on the principle of electromagnetic induction. In this project a changing magnetic flux generated in the primary coil and due to this changing magnetic flux a charge induced in the secondary coil. And due to this induced charge the led glows. It is a very interesting project which you can make for your practical examination or for your science exhibitions. A well prepared investigatory project files also available with this model.
3. Charging and discharging of capacitor
The name of this project is Charging and discharging of capacitor working Model. It shows the charging and discharging phenomenon of capacitor. If you are looking for a project for your practical examination (class 12) then this is the best project for you. A well prepared Investigatory Project pdf is also available with this model.
4. DC Motor Working model
This is the working model of a DC Motor. We have used copper coil, magnet and battery to make this project. It is very simple but impressive project which you can make for your science exhibition or for your practical examination. This project is also equipped with a well prepared investigatory project file.
5. Full wave rectifier
A full wave rectifier is a device which convert complete cycle of alternating current in to pulsating DC. In this model we have used a step down transformer, 2 diode and capacitor to get pure DC supply. It converts 220V AC to 9V DC. It is a very good working model which you can make for your practical examination. This model also equipped with a well prepared Investigatory Project PDF.
6. Half wave rectifier
A half-wave rectifier converts an AC signal to DC by passing either the negative or positive half-cycle of the waveform and blocking the other. For making this project you will need a step down transformer, one diode and one capacitor. It is a very simple and good working model which you can make for your practical examination. This model also equipped with a well prepared Investigatory Project PDF.
7. Electric Generator
An electric generator is a device that converts mechanical energy into electrical energy. It uses the principles of electromagnetic induction to generate an electric current. For making this model we have used a 12V DC motor, an LED, pully etc. It is very good as well as easy to make project which you can make for your science exhibition and practical examination. A well prepared investigatory project pdf is available with this working model.
8. Electromagnet Working Model
An electromagnet is a type of magnet in which the magnetic field is generated by an electric current. Unlike permanent magnets, which have a fixed magnetic field, electromagnets can be controlled by adjusting the current flowing through the wire coils. The construction of an electromagnet involves wrapping a wire coil, usually made of copper or another conductive material, around a magnetic core. The core is often made of a ferromagnetic material such as iron. When an electric current passes through the wire, it creates a magnetic field around the coil. This model also equipped with a well prepared Investigatory Project PDF.
10. Touch Sensor
A touch sensor is a type of input device that detects physical touch or pressure on its surface and converts it into an electrical signal. This project is basically a working model of touch sensor. We have used a transistor, resistor, battery and buzzer for making of this project. It is very good as well as easy to make project which you can make for your science exhibition and practical examination. A well prepared investigatory project pdf is available with this project.
11. Electric door bell
It is a working model of an electric door bell which works like a real door bell. We have used a DC motor, battery, switch, some wooden piece for making this project. By using motor and ice-cream stick we have designed a mechanism which rotate the stick in back and forth direction instead of circular motion, the same mechanism also used in electric hair trimer. It is very good as well as easy to make project which you can make for your science exhibition and practical examination. Unfortunately no investigatory project pdf is available with this project.
12. Water level indicator
It is a working model of water level indicator, you can use this model for knowing the water level of tank installed on roof top. If you are looking for a fantastic project for your science exhibition then this is for you. For making this project you will need 4 transistor, 4 resistor, 4 LED, one battery, one switch and some connecting wire. The making of this project is little hard so, if you have good knowledge of electricity, or of electric circuit then you can make this model by following circuit diagram. No project pdf is available with this model.
13. Li-Fi Project Model
Li-Fi, short for “light fidelity,” is a wireless communication technology that uses light to transmit data. It is an alternative or complementary technology to traditional Wi-Fi, which uses radio waves for data transmission. For making this project you will need a battery, aux cable, small solar panel, LED and resistor. You can use this project for your science exhibition. A well prepared investigatory project pdf is also available with this model.
14. Night sensor switch (LDR)
We have made a circuit which gets on during night and automatically gets off in daylight. The same technology used in street light which automatically gets on in night and again gets off in next morning. We have used LDR for making this circuit. LDR stands for Light Dependent Resistor, which is an electronic component that changes its resistance based on the amount of light falling on it. It is also known as a photoresistor or photocell. This project is also equipped with a well prepared investigatory project PDF.
