Q1. Types of transformers
Ans. 
Transformers are devices that transfer electrical energy between two or more circuits through electromagnetic induction.
• Step-up transformer increases voltage levels (e.g. power distribution)

• Step-down transformer decreases voltage levels (e.g. household appliances)

• Auto transformer has a single winding with multiple taps for voltage adjustment

• Isolation transformer provides electrical isolation between input and output ci...read more

Q3. Why used gear box in conveyor. Ans-Because for speed reduction and high torque.
Ans. 
Gear box is used in conveyor for speed reduction and high torque.
• Gear box helps in reducing the speed of the conveyor system while increasing the torque.

• It allows the motor to run at a higher speed while the conveyor moves at a slower speed.

• Different types of gear boxes are used depending on the application, such as helical, worm, bevel, etc.

• Gear boxes also help in maintaining a constant speed and preventing overloadin...read more

Q4. Why used coupling. Ans-Because for power transmit from one shaft to another shaft.
Ans. 
Couplings are used to transmit power from one shaft to another shaft.
• Couplings are used to connect two shafts together.

• They allow for the transmission of power from one shaft to another.

• Couplings can compensate for misalignment between shafts.

• There are various types of couplings such as rigid, flexible, and fluid couplings.

• Examples of applications include pumps, compressors, and generators.
