Study Notes

Microprocessors and Electronic Components

Microprocessors are used in automated equipment in various industries, cars, phones, cameras, watches, and other devices that store and process information.

Electronic Building Blocks

Common electronic components in circuits include capacitors, diodes, and transistors.
Capacitors store electric charge for a short time before allowing it to flow to other parts of a circuit, and their capacity is measured in farads (F) or microfarads (μF).
Diodes allow electric current to travel through them in only one direction, with the negative end connected closer to the negative terminal of the power supply.

Integrated Circuits and Microprocessors

Integrated circuits contain thousands of miniature electronic components etched onto chips, and are used in devices like watches, calculators, and digital meters.
The first silicon chip was developed in 1958, and by 1965, chips could hold about 30 electronic components.
By 1975, similar-sized chips could hold about 30,000 components, allowing for the production of desktop computers with sophisticated processing capabilities.
Modern methods of producing chips have led to the development of chips with millions of electronic components.
Microprocessors are silicon chips that can store information, process it, and control other electric circuits, and have been used in calculators, computers, and household appliances since 1971.

Electric Circuits

Electric circuits consist of three essential items: a power supply, a load, and a conducting path.
A power supply provides electrical energy, a load converts electrical energy into other useful forms of energy, and a conducting path allows electric charge to flow around the circuit.
Batteries store chemical energy that is transformed into electrical energy through a chemical reaction.
Most household appliances receive electrical energy from a power station via a power outlet.
