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.

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).

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

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.
