Q1. How to work cnc machine
Ans. 
To work a CNC machine, you need to program it with the desired design, set up the materials, and monitor the process for any issues.
• Program the CNC machine with the design using specialized software

• Set up the materials to be cut or shaped according to the programmed design

• Monitor the CNC machine during operation to ensure it is running smoothly and make any necessary adjustments

• Follow safety protocols to prevent accide

Q2. Explane three type geometry
Ans. 
Three types of geometry include Euclidean geometry, non-Euclidean geometry, and projective geometry.
• Euclidean geometry is the study of flat or two-dimensional shapes and their properties.

• Non-Euclidean geometry includes hyperbolic and elliptic geometry, which do not follow the rules of Euclidean geometry.

• Projective geometry deals with the properties of geometric figures that are invariant under projective transformation

Q1. What is a resistor?
Ans. 
A resistor is an electronic component that resists the flow of electrical current.
• Resistors are used to control the amount of current flowing in a circuit.

• They are measured in ohms (Ω) and have color-coded bands to indicate their resistance value.

• Resistors dissipate energy in the form of heat when current flows through them.

• Common types of resistors include carbon film, metal film, and wirewound resistors.

Q2. What is a transistor?
Ans. 
A transistor is a semiconductor device used to amplify or switch electronic signals.
• Transistors are fundamental building blocks of modern electronic devices.

• They can amplify electrical signals, control the flow of current, and act as switches.

• Common types of transistors include bipolar junction transistors (BJTs) and field-effect transistors (FETs).

Q1. Refrigeration cycle ?
Ans. 
Refrigeration cycle is a thermodynamic cycle used in refrigerators and air conditioning systems to transfer heat from a low temperature reservoir to a high temperature reservoir.
• Consists of four main components: compressor, condenser, expansion valve, and evaporator

• Refrigerant is compressed in the compressor, then condensed in the condenser, expanded in the expansion valve, and evaporated in the evaporator

• Heat is absor...read more

Q2. Theory on refrigeration
Ans. 
Refrigeration theory involves the transfer of heat from a low temperature region to a high temperature region using a refrigerant.
• Refrigeration is based on the principles of thermodynamics, specifically the second law which states that heat naturally flows from a higher temperature to a lower temperature.

• The refrigeration cycle consists of four main components: compressor, condenser, expansion valve, and evaporator.
