What are the fundamentals of contemporary electronics?
The fundamentals of contemporary electronics are the basic concepts and principles that govern the behavior and operation of electronic components, devices, circuits, and systems. Some of the fundamentals of contemporary electronics are:
Voltage, current, and resistance
Voltage, current, and resistance are the three basic quantities that describe the electric signals in an electronic circuit. Voltage is the measure of electric potential difference between two points in a circuit. It is measured in volts (V). Current is the measure of electric charge flow through a point in a circuit. It is measured in amperes (A). Resistance is the measure of opposition to electric current flow in a circuit. It is measured in ohms (Ω). Voltage, current, and resistance are related by Ohm's law, which states that voltage equals current times resistance (V = IR). Kirchhoff's laws are two rules that apply to any circuit. Kirchhoff's current law states that the sum of currents entering a node equals the sum of currents leaving a node. Kirchhoff's voltage law states that the sum of voltages around a loop equals zero.
Capacitors and inductors
Capacitors and inductors are two types of electronic components that can store energy in an electric field or a magnetic field, respectively. Capacitors consist of two conductive plates separated by an insulator. Capacitors can store electric charge when a voltage is applied across them. The amount of charge stored depends on the capacitance, which is measured in farads (F). Inductors consist of a coil of wire wrapped around a core. Inductors can store magnetic flux when a current flows through them. The amount of flux stored depends on the inductance, which is measured in henries (H). Capacitors and inductors have an effect on the frequency response of a circuit. They have an opposition to alternating current (AC) flow called reactance, which is measured in ohms (Ω). The reactance of a capacitor decreases as the frequency increases, while the reactance of an inductor increases as the frequency increases.
Diodes and transistors
Diodes and transistors are two types of semiconductor devices that can control the flow of electric signals in a circuit. Diodes consist of two regions of semiconductor material with different doping levels, called p-type and n-type. Diodes allow current to flow only in one direction, from the p-type to the n-type region. Diodes can be used for various purposes, such as rectification, regulation, switching, etc. Transistors consist of three regions of semiconductor material with different doping levels, called emitter, base, and collector. Transistors can amplify or switch electric signals by controlling the current flow from the emitter to the collector using a small voltage applied to the base. Transistors can be used for various purposes, such as amplification, switching, logic, etc.
What are the devices of contemporary electronics?
The devices of contemporary electronics are the electronic components that can perform specific functions or tasks in a circuit or system. Some of the devices of contemporary electronics are:

Actuators are devices that can receive electric signals and convert them into physical actions or movements, such as rotation, vibration, sound, light, etc. Sensors and actuators can be used for various purposes, such as monitoring, control, feedback, etc.
LEDs and displays
LEDs and displays are two types of light-emitting and visual devices that can produce or show images or information. LEDs are devices that can emit light when a current flows through them. LEDs can be used for various purposes, such as indicators, illumination, communication, etc. Displays are devices that can show images or information using pixels or segments that can change color or brightness.
