Flashcards created from lecture notes on basic electronics, covering foundational definitions, active and passive components, fundamental laws, electronic displays, real-world applications, and emerging technologies.

Who prepared the Basic Electronics lecture presentation?

Ryan Marc R. Escorel.

What is the definition of electronics?

Electronics is the study of how to control the flow of electrons or electric energy. It involves using electronic components to create circuits that perform specific functions.

Into what two main categories can electronic components be divided?

Active components and passive components.

What are active components, and what are three examples?

Active components are devices that can control the flow of electrons and produce a signal or power output. Examples include transistors, diodes, and integrated circuits.

What are passive components, and what are three examples?

Passive components are devices that do not control the flow of electrons but instead resist, store, or filter electrical signals. Examples include resistors, capacitors, and inductors.

What is the function of a resistor in a circuit?

A resistor limits the flow of current in a circuit and is commonly used to adjust voltage levels or current flow.

How does a capacitor operate in relation to DC and AC signals?

A capacitor stores electrical energy in an electric field; it blocks DC signals and allows AC signals to pass through.

How does an inductor operate in relation to AC and DC signals?

An inductor stores electrical energy in a magnetic field; it blocks AC signals and allows DC signals to pass through.

What is the function of a diode in an electronic circuit?

A diode allows current to flow in one direction only and protects other components from damage caused by reverse voltage.

What are the primary functions of a transistor?

A transistor can amplify or switch electronic signals to control the flow of current and voltage.

What is an integrated circuit (IC)?

An integrated circuit is a miniaturized electronic circuit that contains multiple components, such as transistors, diodes, and capacitors, on a single chip.

What is an electronic circuit?

An electronic circuit is a combination of electronic components interconnected to perform a specific function.

How do current and voltage behave in series versus parallel circuits?

In a series circuit, components are connected end-to-end and the same current flows through all of them. In a parallel circuit, current flows through multiple paths and the voltage is the same across all components.

What does Ohm's Law state?

Ohm's Law states that the current through a conductor between two points is directly proportional to the voltage across the two points and inversely proportional to the resistance between them.

What is Kirchhoff's Current Law (KCL)?

Kirchhoff's Current Law states that the sum of the currents entering a node or junction is equal to the sum of the currents leaving that node or junction.

What is Kirchhoff's Voltage Law (KVL)?

Kirchhoff's Voltage Law states that the sum of the voltages in a closed loop is equal to zero.

What is the purpose of a transistor amplifier circuit?

It uses transistors to amplify electronic signals, commonly increasing the strength of a weak signal in audio and radio circuits.

What defines an electronic device?

An electronic device is any device that runs on electricity and uses digital signals to perform a specific function.

What is a light-emitting diode (LED)?

A light-emitting diode (LED) is a semiconductor device that emits light when current flows through it.

What is a liquid crystal display (LCD)?

A liquid crystal display (LCD) is a type of flat-panel display that uses liquid crystals to produce an image.

What is a cathode ray tube (CRT)?

A cathode ray tube (CRT) is a type of vacuum tube that uses an electron beam to create an image on a phosphorescent screen.

How do digital cameras capture and produce images?

They use sensors to convert light into electronic signals, which are then processed by electronic circuits to produce an image.

What technologies are highlighted for driving the future of electronics?

Nanotechnology, quantum computing, and the Internet of Things (IoT).

What is nanotechnology, and what specific example material is noted in the text?

Nanotechnology involves manipulating matter at the nanoscale level to create smaller, more efficient components. An example mentioned is Silicone nanowires.

What is quantum computing?

Quantum computing is a new computing paradigm relying on quantum mechanics to perform calculations and solve complex problems beyond classical computing capabilities.

What is the Internet of Things (IoT)?

The Internet of Things (IoT) is a network of interconnected devices that can communicate with each other and with the internet to perform tasks autonomously.
