GVK Emergency Management and Research Institute Interview Questions and Answers

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

• Motors can be classified into different types such as DC motors, AC motors, and stepper motors.

• The basic working principle of a motor involves the interaction of magnetic fields to generate force and motion.

• In a DC motor, current flows through a coil within a magnetic field, creating a force that rotates the motor shaft.

• In an AC motor, the direction of the current changes periodically...read more

Switch is used to control the flow of electricity, isolator is used for isolating a circuit, and circuit breaker is used for protecting the circuit from overloads.

• Switch is used to open or close an electrical circuit, allowing or stopping the flow of electricity.

• Isolator is used to disconnect a circuit from the power supply for maintenance or repair purposes.

• Circuit breaker is a device designed to protect an electrical circuit from damage caused by overload or short circuit.

• E...read more

Switch is used to make or break an electrical circuit, isolator is used for isolating a circuit for maintenance, and circuit breaker is used for protecting the circuit from overloads and short circuits.

• Switch is used to manually open or close an electrical circuit.

• Isolator is used to isolate a circuit for maintenance purposes, ensuring no current flows through it.

• Circuit breaker is a safety device that automatically interrupts the flow of current in a circuit in case of overl...read more

There are three main types of faults: normal faults, reverse faults, and strike-slip faults.

• Normal faults occur when the hanging wall drops down relative to the footwall. Example: Basin and Range Province in the western United States.

• Reverse faults occur when the hanging wall moves up relative to the footwall. Example: Rocky Mountains in North America.

• Strike-slip faults occur when the blocks slide past each other horizontally. Example: San Andreas Fault in California.

Conveyor line experience in JSPL is relevant to the Production Engineer role.

• JSPL has a large-scale conveyor system for transporting raw materials and finished products.

• Experience with conveyor systems is important for optimizing production efficiency.

• Knowledge of conveyor maintenance and troubleshooting is also valuable.

• JSPL's conveyor system includes various types of conveyors such as belt, screw, and bucket conveyors.

• Experience with conveyor automation and control systems ...read more

A transformer is a 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.

• There are two main types of transformers: step-up transformers and step-down transformers.

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

• Other types of transformers include isolation transformers, autotransformers, and dis...read more

There are two main types of motors: AC motors and DC motors.

• AC motors: Alternating current motors that are commonly used in household appliances and industrial applications.

• DC motors: Direct current motors that are often used in battery-operated devices and automotive applications.
