Q5. What is tha current law
Ans. 
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.
• Current (I) = Voltage (V) / Resistance (R)

• It helps in calculating the current flowing through a circuit based on the voltage and resistance values.

• It is represented by the formula I = V/R.

• Ohm's Law is fundamental in understanding and analy

Q3. All the laws of thermodynamics and haet transfer in thermal engineering .
Ans. 
Thermodynamics and heat transfer are fundamental principles in thermal engineering, governing energy transfer and conversion.
• First law of thermodynamics: Conservation of energy, stating that energy cannot be created or destroyed, only transferred or converted.

• Second law of thermodynamics: Entropy always increases in a closed system, leading to the direction of heat flow.

• Third law of thermodynamics: As temperature appro...read more

Q5. All the process in RAC .
Ans. 
RAC stands for Refrigeration and Air Conditioning. It involves various processes like compression, condensation, expansion, and evaporation.
• Compression: The refrigerant gas is compressed to increase its temperature and pressure.

• Condensation: The high-pressure gas releases heat and condenses into a liquid.

• Expansion: The liquid refrigerant passes through an expansion valve, reducing its pressure and temperature.

• Evaporati...read more

Q1. What is the heat treatment
Ans. 
Heat treatment is a process used to alter the physical and sometimes chemical properties of a material through controlled heating and cooling.
• Heat treatment involves heating a material to a specific temperature, holding it at that temperature for a certain amount of time, and then cooling it at a controlled rate.

• The purpose of heat treatment is to improve the material's hardness, strength, toughness, ductility, and oth...read more

Q1. What is the magnetic particle test procedure
Ans. 
Magnetic particle test is a non-destructive testing method used to detect surface and near-surface flaws in ferromagnetic materials.
• The test involves magnetizing the component, applying magnetic particles to the surface, and inspecting for indications of defects.

• Defects such as cracks, laps, seams, and inclusions can be detected using this method.

• The test can be performed using either dry magnetic powder or wet fluores...read more
