Mangalam Organics Instrumentation Technician Interview Questions and Answers

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

• Motors can be found 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 winding components to facilitate the conversion of energy.

• Examples of motors include electric fa

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

• Consists of two coils of wire, known as primary and secondary coils

• 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 in electr...read more

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

A transformer is an electrical device that changes the voltage and current levels while maintaining the frequency, commonly used for stepping up or stepping down voltage.

• Transformers consist of primary and secondary coils wound around a core made of ferromagnetic material.

• They work on the principle of electromagnetic induction, where changing current in the primary coil induces a voltage in the secondary coil.

• Step-up t...read more

A motor is an electrical device that converts electrical energy into mechanical energy.

• Converts electrical energy to mechanical energy

• Used in various applications such as industrial machinery, appliances, vehicles, etc.

• Types include AC motors, DC motors, servo motors, etc.

• Common examples include electric fans, washing machines, electric vehicles, etc.

There are three main types of motors: AC motors, DC motors, and universal motors.

• AC motors run on alternating current and are commonly used in household appliances.

• DC motors run on direct current and are often found in battery-operated devices.

• Universal motors can run on both AC and DC power sources, making them versatile for various applications.

MCB stands for Miniature Circuit Breaker, a device designed to protect electrical circuits from overloads and short circuits.

• MCB is a type of circuit breaker that automatically switches off electrical circuits during abnormal conditions like overload or short circuit.

• It is commonly used in residential and commercial electrical installations to provide protection to the electrical system and prevent damage to appliances...read more

A diesel generator (DG) is a type of generator that uses a diesel engine to generate electricity.

• DGs are commonly used as backup power sources in case of power outages.

• They are also used in remote locations where grid power is not available.

• DGs are available in various sizes and capacities to suit different power requirements.

• Regular maintenance and fuel supply are essential for the proper functioning of a DG.

• Examples ...read more
