Q4. How the load increase and decrease in generators happen, explain
Ans. 
Load increase and decrease in generators occur based on the demand for electricity.
• Load increase happens when more electrical appliances are turned on, requiring more power from the generator.

• Load decrease occurs when electrical appliances are turned off, reducing the power demand on the generator.

• Generators adjust their output based on the load changes to maintain a stable power supply.

• Load shedding may be implemented...read more

Q2. Centrifugal force applications
Ans. 
Centrifugal force is the outward force experienced by an object moving in a circular path.
• Centrifugal force is not a real force, but rather a perceived force due to inertia.

• It is used in various applications such as centrifuges for separating fluids, amusement park rides, and washing machines.

• Centrifugal force increases with the speed of rotation and the mass of the object.

• It is important to consider centrifugal force ...read more
