Q3. What is enthalpy in thermodynamics?
Ans. 
Enthalpy is the sum of internal energy and pressure-volume work done by a system.
• Enthalpy is a thermodynamic property of a system.

• It is represented by the symbol 'H'.

• It is defined as the sum of internal energy and pressure-volume work done by a system.

• Enthalpy change is given by the formula ΔH = ΔU + PΔV.

• It is used to measure the heat content of a system at constant pressure.

• Enthalpy is important in chemical reactions ...read more

Q4. What is coupling and explain
Ans. 
Coupling refers to the degree of interdependence between two components in a system.
• Coupling is a measure of how closely connected two components are in a system.

• It can be classified as tight coupling or loose coupling.

• Tight coupling means that the components are highly dependent on each other, while loose coupling means that they are more independent.

• Coupling can affect the maintainability, scalability, and flexibilit...read more

Q2. What is transmission losses
Ans. 
Transmission losses refer to the energy lost during the transmission of electricity from power plants to end users.
• Transmission losses occur due to resistance in power lines and transformers.

• Factors affecting transmission losses include distance, weather conditions, and the quality of equipment.

• Examples of reducing transmission losses include using high voltage transmission lines and improving grid infrastructure.
