Birla Corporation Interview Questions, Process, and Tips

Ohm's Law states that the current flowing through a conductor is directly proportional to the voltage applied across it, and inversely proportional to the resistance of the conductor.

• Ohm's Law is represented by the formula V = IR, where V is voltage, I is current, and R is resistance.

• It helps in calculating the relationship between voltage, current, and resistance in an electrical circuit.

• For example, if a circuit has ...read more

Transformer protection refers to the measures taken to ensure the safe operation of transformers and prevent damage.

• Overcurrent protection: Protects against excessive current flow.

• Overvoltage protection: Safeguards against high voltage levels.

• Overtemperature protection: Prevents overheating of the transformer.

• Differential protection: Detects internal faults by comparing input and output currents.

• Buchholz relay: Detects...read more

My hobbies include playing the guitar, hiking, and photography.

• Playing the guitar helps me relax and express my creativity.

• Hiking allows me to explore nature and stay active.

• Photography is a passion of mine, capturing moments and scenes in a unique way.

The differential is a device that allows the wheels on an axle to rotate at different speeds while still receiving power from the engine.

• Allows wheels on the same axle to rotate at different speeds

• Transfers power from the engine to the wheels

• Helps with cornering by allowing the outer wheel to rotate faster than the inner wheel

• Consists of gears that distribute power evenly to the wheels

The dumper cooling system is responsible for maintaining the optimal temperature of the dumper to prevent overheating.

• Regularly check the coolant levels and top up if necessary.

• Inspect the radiator for any leaks or damage.

• Clean the radiator fins to ensure proper airflow.

• Monitor the temperature gauge regularly while operating the dumper.

• If the dumper overheats, stop immediately and allow it to cool down before continuin

Work permit system is a formal process to ensure safety during maintenance activities.

• Obtain necessary permits before starting any maintenance work.

• Identify potential hazards and implement necessary safety measures.

• Communicate with all involved parties about the work being done and safety precautions.

• Regularly review and update work permits as needed.

• Examples: hot work permit, confined space entry permit, electrical wo

The grade of oil used in a hydraulic system depends on the system's requirements and manufacturer recommendations.

• The grade of oil used in a hydraulic system is typically specified by the system manufacturer.

• Common grades of hydraulic oil include ISO VG 32, ISO VG 46, and ISO VG 68.

• The grade of oil chosen should meet the viscosity and performance requirements of the hydraulic system.

• Using the wrong grade of oil can lea...read more
