Mangalam Organics Instrumentation Technician Interview Questions and Answers

A motor is a device that converts electrical energy into mechanical energy to produce motion.

• Motors are commonly used in various applications such as industrial machinery, household appliances, and vehicles.

• There are different types of motors including AC motors, DC motors, and servo motors.

• Motors consist of a rotor, stator, and various components such as coils, magnets, and brushes.

• Examples of motors include electric

VCB stands for Vacuum Circuit Breaker, a type of circuit breaker that uses vacuum as the arc quenching medium.

• VCB is a type of circuit breaker that uses vacuum as the arc quenching medium.

• It is used to interrupt the current flow in case of a fault or overload in the electrical system.

• VCBs are commonly used in medium voltage applications.

• They are preferred over other types of circuit breakers due to their high reliabili

A transformer is an electrical device that transfers electrical energy between two or more circuits through electromagnetic induction.

• Consists of two coils of wire (primary and secondary) wrapped around a core

• Primary coil receives electrical energy and creates a magnetic field

• Magnetic field induces a voltage in the secondary coil, transferring energy to the secondary circuit

• Used to step up or step down voltage levels i

AC and DC motors are types of electric motors used for different applications. AC motors run on alternating current while DC motors run on direct current.

• AC motors run on alternating current, which means the direction of current flow changes periodically.

• DC motors run on direct current, where the current flows in one direction consistently.

• AC motors are commonly used in household appliances, industrial machinery, and H...read more
