Q2. Working principle of Loadcell
Ans. 
Loadcell works on the principle of converting force into an electrical signal.
• Loadcell measures force or weight by converting it into an electrical signal

• It typically consists of a metal structure with strain gauges attached to it

• When force is applied, the metal structure deforms, causing a change in resistance of the strain gauges

• This change in resistance is converted into an electrical signal proportional to the forc...read more

Q2. What is compressor & how it work?
Ans. 
A compressor is a mechanical device that increases the pressure of a gas by reducing its volume.
• Compressors are commonly used in refrigeration, air conditioning, and gas turbines.

• They work by taking in a gas at a low pressure and volume, and then reducing the volume to increase the pressure.

• This process is achieved through the use of pistons, vanes, or rotating impellers.

• The compressed gas is then released at a higher
