BJT DefinitionA Bipolar Junction Transistor (BJT) is defined as a three-terminal semiconductor device used for amplification and switching.Applications of Bipolar Junction TransistorThere are two types of applications of bipolar junction transistor, switching and amplification.Transistor as a SwitchIn switching applications, a transistor operates in either the saturation or cutoff region. In the cutoff region, the transistor acts as an open switch, while in saturation, it acts as a closed switch

What are the Applications of Hall Effect ?Hall Effect DefinitionThe Hall effect is defined as the deflection of charge carriers in a current-carrying conductor when placed in a magnetic field.Determine the Type of SemiconductorThe direction of the Hall voltage helps identify if a semiconductor is n-type or p-type.Calculate the Carrier ConcentrationThe Hall effect is used to find the concentration of electrons and holes in a semiconductor.Determine the Mobility (Hall Mobility)The Hall coefficient

Servo Motor DefinitionA servo motor is defined as a motor that operates on the principle of a servomechanism, crucial for precise position control.Robotics ApplicationsOne of the most popular applications of servo motors is in robotics. For example, a pick and place robot uses servo motors to pick an object from one position and place it in another. This precise movement is essential for the robot’s functionality.Now, in order to pick an object from position A and place it in position B the moto

Induction Generator DefinitionAn induction generator (also known as an asynchronous generator) is defined as an induction machine used to generate electricity.Operating PrincipleInduction generators work when the slip is negative, achieved by increasing the prime mover speed beyond synchronous speed.Magnetizing Current RequirementThey require external sources for magnetizing current and reactive power, often provided by supply mains or other generators.Self-Excited GeneratorsThis type, also know

DC Generator DefinitionA DC generator is a device that converts mechanical energy into direct current electricity for various applications.Application of Separately Excited DC Generators These type of DC generators are generally more expensive than self-excited DC generators, because they need a separate excitation source. This restricts their applications. They are used where self-excited generators do not perform well. Because of their ability of giving wide range of voltage output, they are g

What is The Applications of Induction Motor?Induction Motor DefinitionAn induction motor is an AC electric motor that operates on the principle of electromagnetic induction.Types of Induction MotorsSquirrel cageA squirrel cage induction motor is a type of induction motor that has a cylindrical rotor with slots parallel to the shaft. The slots contain uninsulated conductor bars of aluminum or copper that are short-circuited by heavy end rings at both ends of the rotor. The rotor resembles a cage
