Q1. SEM explain working method etc
Ans. 
SEM stands for Scanning Electron Microscope, a type of microscope that uses electrons to create high-resolution images of samples.
• SEM uses a focused beam of electrons to scan the surface of a sample

• The electrons interact with the atoms in the sample, producing signals that can be used to create an image

• SEM provides high-resolution images with magnifications up to 1,000,000x

• It is commonly used in materials science, biol

Q1. What are diodes and semiconductor
Ans. 
Diodes are electronic components that allow current to flow in one direction only, while semiconductors are materials with conductivity between that of insulators and conductors.
• Diodes are used in rectifiers to convert AC to DC power

• Semiconductors are used in electronic devices like transistors and integrated circuits

• Diodes have a forward voltage drop, typically around 0.7V for silicon diodes

• Semiconductors have a band

Q1. How to check compressor is okey??
Ans. 
Check compressor by monitoring performance, inspecting for leaks, and listening for unusual noises.
• Monitor performance by checking pressure levels and temperature readings.

• Inspect for leaks by using a soap solution to detect air bubbles.

• Listen for unusual noises such as knocking or rattling sounds.

• Check for proper lubrication and ensure all connections are secure.

• Inspect the compressor motor for any signs of overheatin

Q2. Explain VCR'S cycle with diagram?
Ans. 
VCR's cycle involves recording and playback of video content using magnetic tape.
• VCR records video content onto magnetic tape during the recording phase

• During playback, the recorded video content is read from the tape and displayed on the screen

• The cycle involves the user inserting a tape, recording content, and then playing back the recorded content

• VCR's cycle can be represented in a diagram showing the flow of record

Q3. What is the reason of machine not work properly cooling?
Ans. 
The machine may not work properly due to issues with the cooling system, such as low refrigerant levels or a malfunctioning compressor.
• Low refrigerant levels can lead to inadequate cooling capacity

• A malfunctioning compressor can result in poor cooling performance

• Blocked air filters or condenser coils can restrict airflow and reduce cooling efficiency

Q4. There are some reason of no cooling in machine. 1. Dust in Evaporator Coil 2. No Refrigerant found in Unit 3. Do not pumping Compressor properly 4. Chocked expansion Valve
Ans. 
Possible reasons for no cooling in a machine include dust in evaporator coil, lack of refrigerant, improper compressor pumping, and a chocked expansion valve.
• Check for dust accumulation in the evaporator coil and clean if necessary

• Inspect for any leaks or lack of refrigerant in the unit

• Ensure the compressor is functioning properly and pumping refrigerant effectively

• Check for any blockages or issues with the expansion v
