Electronics is the science of controling and manipulating the flow of electrons using various devices in an electric circuit design.
Electronics has allowed the development of much modern technology including radio and computers.
ELECTRON TUBE
⚜ What is an Electron Tube? ⚜
The Electron Tube is a vacuum tube that uses Thermionic Emmision to control electron flow through the vacuum.
From the Electron Tube were derived the Diode and the Triode electronic devices.
DIODE
⚜ What is a Diode? ⚜
The original Diode was an electronic control device that used an electron tube.
The Diode acts like a one-way switch as it allows electric current to flow in only one direction.
Most Diodes used today use semiconductor PN Junctions.
The Zener Diode is a special semiconductor diode that begins conducting large current after a unique breakdown voltage is reached.
TRIVIA
🔔 QUESTION : What is the narrow band of separated space charge between the N and P regions of a Diode called?
💡 Hover or Tap for the ANSWER! 💡
The narrow band of separated space charge between the N and P regions of a Diode is called a PN Junction.
TRANSISTOR
⚜ What is a Transistor? ⚜
A transister is a three-terminal electronic switch invented in 1957 using Semiconductors.
The Junction Transister has Base, Emitter and Collector terminals.
The Transistor uses doped semiconductor regions called N, where the current carriers are electrons and P, where the current carriers are electron holes.
INDUCTOR
⚜ What is an Inductor? ⚜
An Inductor is an electronic device that stores energy in the form of a magnetic field around the windings of a conductor which usually surrounds a ferromagnetic medium.
Inductors are often used in filters and LC circuits.
SEMICONDUCTOR
⚜ What is a Semiconductor? ⚜
The Semiconductor is the principle material that has allowed the development of Solid State devices.
Important Semiconductors are Silicon and Germanium.
The Semiconductor is a material that conducts electricity better than an insulator but not as well as a conductor.
Semiconductors are doped with elements such as Phosphorus and Boron, among others, to increase and control their conductive properties.

THERMISTER
⚜ What is a Thermister? ⚜
A Thermister is an electronic device used to measure temperature.
The Thermister is made from pure (intrinsic) semiconductor material, such as Silicon.
With Thermisters, the higher the ambient temperature, the lower the resistance of the thermister.
RECTIFIER
⚜ What is a Rectifier? ⚜
A Rectifier is an electronic circuit used to convert Alternating current (AC) into Direct current (DC).
Rectifiers are frequently used in DC Power Supplies.
Types of Rectifiers include the Half-wave rectifier, the Full-wave rectifier and the Bridge rectifier.
CAPACITOR
⚜ What is a Capacitor? ⚜
A Capacitor is an electronic device that stores energy in the form of an electric field stored in a dielectric sandwiched between conducting plates.
Capacitors are often used in filters and LC circuits.
LED
⚜ What is an LED? ⚜
An LED is a Light-Emitting Diode.
An LED produces light when some of the electron carriers flowing with the current through the LED recombine with hole carriers within the PN junction and emit a photon.
