Indian Space Research Organisation Interview Questions, Process, and Tips

There are three laws of thermodynamics. Each law has specific applications. dB Amp is not related to thermodynamics.

• The first law of thermodynamics, also known as the law of energy conservation, states that energy cannot be created or destroyed, only transferred or transformed.

• The second law of thermodynamics states that the entropy of an isolated system always increases over time.

• The third law of thermodynamics states...read more

Spark plug ignites fuel-air mixture in IC engines. DTSI improves combustion efficiency. 2-stroke and 4-stroke engines differ in number of strokes per cycle.

• Spark plug ignites the fuel-air mixture in the combustion chamber

• DTSI (Digital Twin Spark Ignition) is a technology used to improve combustion efficiency by using two spark plugs

• 2-stroke engines complete one power stroke in two strokes of the piston, while 4-stroke ...read more

Humidity ratio is measured using two types of instruments: psychrometers and hygrometers.

• Psychrometers measure humidity ratio by comparing the readings of two thermometers: a dry-bulb and a wet-bulb thermometer.

• Hygrometers measure humidity ratio using various principles such as electrical resistance, capacitance, or condensation.

• A 1 ton refrigerator refers to the cooling capacity of the refrigerator, which is equivalen...read more

• I enjoy working on projects that involve designing and optimizing electronic components for efficient heat dissipation.

• I have experience in conducting thermal analysis and simulations to ensure proper heat transfer in electronic devices.

• I find it fascinat...read more

The choice between Al and Mg for designing depends on the specific requirements and constraints of the project.

• Aluminum (Al) is lightweight, corrosion-resistant, and has good thermal conductivity, making it suitable for applications where weight reduction is important, such as aerospace.

• Magnesium (Mg) is even lighter than aluminum, but it has lower strength and is more prone to corrosion. It is commonly used in automot...read more

A rocket is a vehicle that propels itself through the atmosphere or space, while a missile is a weapon that is guided towards a target.

• Rockets are used for space exploration, satellite launches, and transportation, while missiles are used for military purposes.

• Rockets are typically unmanned and used for peaceful purposes, while missiles are often armed and used for warfare.

• Rockets are designed to carry payloads such as...read more

NA is a non-profit organization dedicated to providing support and resources to individuals in need.

• NA offers various programs and services to help individuals overcome addiction and maintain sobriety.

• They provide support groups, counseling, and educational resources for individuals and their families.

• NA follows a 12-step program similar to Alcoholics Anonymous (AA) to help individuals recover from addiction.

• The organi...read more

Lack of growth opportunities and limited autonomy

• Limited opportunities for professional development and advancement

• Lack of autonomy and micromanagement

• Inadequate support or resources to perform job effectively

• Poor work-life balance or excessive workload

• Unhealthy work environment or toxic culture

I am open to discussing salary based on the responsibilities and opportunities offered by the position.

• I am flexible and willing to negotiate based on the job requirements.

• I value fair compensation for my skills and experience.

• I am open to discussing benefits and other forms of compensation.

• I am looking for a salary that aligns with industry standards and my qualifications.

• I am interested in opportunities for growth an

Yes

• In asynchronous transmission, synchronizing pulses are not necessary.

• Start and stop bits are used to synchronize the transmission.

• Start bit indicates the beginning of a character and stop bit indicates the end.

• The start and stop bits help the receiver identify the boundaries of each character.

• Examples of asynchronous transmission include RS-232 and UART.

Transformers work on the principle of electromagnetic induction.

• Transformers use two coils of wire, known as the primary and secondary coils.

• When an alternating current flows through the primary coil, it creates a changing magnetic field.

• This changing magnetic field induces a voltage in the secondary coil.

• The ratio of the number of turns in the primary and secondary coils determines the voltage transformation.

• Transform...read more
