National Fertilizers Assistant Technician Interview Questions and Answers

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

• Transformers are used to increase or decrease voltage levels in electrical circuits.

• They consist of two coils of wire, known as the primary and secondary coils, wrapped around a core.

• Step-up transformers increase voltage levels, while step-down transformers decrease voltage levels.

• Transf...read more

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.

The type of pump gearbox reactor depends on the specific application and requirements.

• The pump gearbox reactor can be a centrifugal pump, positive displacement pump, or other types depending on the application.

• The gearbox can be a single-stage or multi-stage design.

• The reactor can be a batch or continuous process.

• Examples include chemical processing, oil refining, and power generation.

Flowmeter measures the rate of fluid flow through a pipe or channel.

• Flowmeter works on the principle of measuring the velocity of the fluid and multiplying it with the cross-sectional area of the pipe or channel.

• There are different types of flowmeters such as differential pressure flowmeters, positive displacement flowmeters, electromagnetic flowmeters, ultrasonic flowmeters, etc.

• Flowmeters are commonly used in industr...read more
