Electromagnetic Induction.

Electromagnetic Induction is the production of electromotive force or emf across an electric conductor in a changing magnetic field. Electromagnetic induction first discovered by Michael Faraday in 1831 has found many applications today. These include electrical components such as inductors and transformers and electrical devices such as electric motors and generators. APPLICATIONS ELECTRIC GENERATORS :…

Robot welding

Robot welding is the use of robots which have been programmed for the welding process. These robots are mechanized and programmable and completely automate the welding process which includes both performing the welding process and handling the part. Some processes such as gas metal welding are not necessarily equivalent to robot welding even when the…

Transistors.

A transistor is a semiconductor device used to amplify or switch electronic signals and electrical power. It is composed of semiconductor material usually with at least three terminals for connection to an external circuit. A voltage or current applied to one pair of the transistor’s terminals controls the current through another pair of terminals. Since…

Electric Vehicles

An electric vehicle used electric motors or traction motors for propulsion. Electric vehicles have been used since the 19th century when electricity was preferred to the internal combustion engine due to the level of comfort and ease of operation it offered it’s users. However, the internal combustion engine became the dominant mode of propulsion for…

Radar

Radar or Radio Detection and Ranging is a system of detecting objects using radio waves. Radar employs radio waves to determine the range, angle and velocity of objects such as aircraft, missiles, ships, motor vehicles etc. A radar system consist of a transmitter producing electromagnetic waves in radio or microwave domain, a transmitting and receiving…

Integrated Circuits

An integrated circuit or IC, also known as chip or microchip is a set of electronic circuits on one small flat piece of semiconductor material usually silicon. The integration of large numbers of tiny MOS transistors into a small chip results in circuits that are many times smaller, faster and less expensive than those constructed…

Semiconductors

A semiconductor is a material whose electrical conductivity value falls between a conductor such as an iron rod and an insulator such as glass. Semiconductors are employed in the manufacture of various kinds of electronic devices such as diodes, transistors and integrated circuits. These devices have found wide applications because of their reliability, compactness, power,…

3D Printing

3D printing involves building a three dimensional object from a computer aided design model by successively adding materials layer by layer on top of each other using a 3D printing machine. Within the last decade 3D printing usage has increased dramatically that this technique is now used for industrial applications such as building apartments and…

Air Compressor

<a An air compressor is a device used to compress atmospheric air taken in through inlet valves and compressed to a high pressure, the compressed air being used for various purposes such as cleaning, spray painting, pneumatic operations, starting the main engine, etc. Air compressors force air into a tank, increasing its pressure. When the…

Sonar

<!– wp:paragraph Sonar or Sound Navigation Ranging is a technology which involves the use of sound to detect vessels and other objects underwater or on the surface to aid navigation and avoid collisions. Sonar are of two types: active sonar and passive sonar. Active sonar emits pulses of sounds and listen to echoes from other…
