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. 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.
