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.
