What is Electronics?

Electronics is the branch of science that deals with the study of flow and control of electrons (electricity) and the study of their behavior and effects in vacuums, gases, and semiconductors, and with devices using such electrons. This control of electrons is accomplished by devices that resist, carry, select, steer, switch, store, manipulate, and exploit the electron.

Definition of Electronics: The branch of physics that deals with the emission and effects of electrons and with the use of electronic devices. Electronics refers to the flow of charge (moving electrons) through non-metal conductors (mainly semiconductors), whereas electrical refers to the flow of charge through metal conductors

Definition of Electrical:
relating to or concerned with electricity; "an electrical engineer"; "electrical and mechanical engineering industries"

Difference in “Electronics” and “Electrical”:

deals with flow of charge (electron) through non-metal conductors (semi-conductors).

Electrical deals with the flow of charge through metal conductors.

Example: Flow of charge through silicon which is not a metal would come under electronics whereas flow of charge through copper which is a metal would come under electrical.

Basic Rules of Electrical Circuit

* The current entering any passive circuit equals the current leaving it, regardless of the component configuration.

* Electricity can kill you!

Basics of Electronics: In this section of this electronics website, we learn the basics of electronics including electronics circuits, PCB (Printed Circuit Board), Electronics Design, Laws of Electronics.
Electronics Definitions: Electronics is the branch of science that deals with the study of flow and control of electrons (electricity) and the study of their behavior and effects in vacuums, gases, and semiconductors, and with devices using such electrons.
Rules of Electrical Circuits: * A voltage of 1V across a resistance of 1 Ohm will cause a current flow of 1 Amp, and the resistor will dissipate 1 Watt (all as heat).
Wiring Symbols: There are many different representations for basic wiring symbols, and these are the most common.  The conventions I use for wires crossing and joining are marked with a star (*) - the others are a small sample of those in common use, but are fairly representative.  Many can be worked out from their position in the circuit diagram (schematic).
What is an electronic circuit? A circuit is a structure that directs and controls electric currents, presumably to perform some useful function. The very name "circuit" implies that the structure is closed, something like a loop.
Voltage: Voltage is something is a type of "pressure" that drives electrical charges through a circuit.
Bodies with
opposite charges attract, they exert a force on each other pulling them together. The magnitude of the force is proportional to the product of the charge on each mass.
Current: Charge is mobile and can flow freely in certain materials, called conductors. Metals and a few other elements and compounds are conductors. Materials that charge cannot flow through are called insulators. Air, glass, most plastics, and rubber are insulators, for example. And then there are some materials called semiconductors, that seemed to be good conductors sometimes but much less so other times. Silicon and germanium are two such materials. The flow of charge is called electrical current. Current is measured in amperes (a), amps for short (named after another French scientist who worked mostly with magnetic effects).
What is charge?  Charge may be defined as the quantity of unbalanced electricity in a body (either positive or negative) and construed as an excess or deficiency of electrons. Charge comes in two forms, positive (+) , and  negative charge ( - ) .
Batteries: Charges can be separated by several means to produce a voltage. A battery uses a chemical reaction to produce energy and separate opposite sign charges onto its two terminals. As the charge is drawn off by an external circuit, doing work and finally returning to the opposite terminal, more chemicals in the battery react to restore the charge difference and the voltage. The particular type of chemical reaction used determines the voltage of the battery, but for most commercial batteries the voltage is about 1.5 V per chemical section or cell.
Resistors: A Resistor is an electrical device that resists the flow of electrical current. It is a passive device used to control, or impede the flow of, electric current in an electric circuit by providing resistance, thereby developing a drop in voltage across the device. The value of a resistor is measured in ohms and represented by the Greek letter capital omega. Resistors usually have a brown cylindrical body with a wire lead on each end, and colored bands that indicate the value of the resistor.
Ohm’s Law: Ohm's law describes the relationship between voltage, V , which is trying to force charge to flow, resistance, R , which is resisting that flow, and the actual resulting current I .
Power: Power is the Electric energy produced per unit time.
Capacitors: In simple words, we can say that a capacitor is a device used to store and release electricity, usually as the result of a chemical action. Also referred to as a storage cell, a secondary cell, a condenser or an accumulator. A Leyden Jar was an early example of a capacitor.
Inductors: An inductor is an electrical device (typically a conducting coil) that introduces inductance into a circuit. An inductor is a passive electrical component designed to provide inductance in a circuit. It is basically a coil of wire wrapped around an iron core. simplest form an inductor is made up of a coil of wire. The inductance measured in henrys, is proportional to the number of turns of wire, the wire loop diameter and the material or core the wire is wound around.
Semiconductor devices: A conductor made with semiconducting material. Semiconductors are made up of a substance with electrical properties intermediate between a good conductor and a good insulator. A semiconductor device conducts electricity poorly at room temperature, but has increasing conductivity at higher temperatures. Metalloids are usually good semiconductors.
Silicon: Silicon, atomic number 14 on the periodic table, is a semiconducting material from which integrated circuits (computer chips of all types--processors, memory chips, etc.; CCDs; transistors; etc.) are created.

Silicon is one of the most common elements. Silicon is also the semiconductor material out of which almost all modern transistors are made.
Diodes: A Diode is an electronic device that allows current to flow in one direction only. It is a semiconductor that consists of a p-n junction. They are used most commonly to convert AC to DC, because they pass the positive part of the wave, and block the negative part of the AC signal, or, if they are reversed, they pass only the negative part and not the positive part.
Electronic Component name abbreviations: Here is a list of Electronic Component name abbreviations widely used in the electronics industry:

AE: aerial, antenna           B: battery          BR: bridge rectifier

Electronic Components and Parts: Electronic components are basic electronic element or electronic parts usually packaged in a discrete form with two or more connecting leads or metallic pads. Some of the main Electronic Components are: resistor, capacitor, transistor, diode, operational amplifier, resistor array, logic gate etc.
History of Electronics: It is important to know the History of Electronics (technology) so students better understand their electronic gadgets they use everyday on an increasing bases. That is, cell phones, ATMs, calculators, cars, fax machines, computers, copiers, radios, TV, etc. To understand the interesting history of these electronic devices helps explain why science and technology are important, too. Without these technologies and electronics, our status in the world community would be diminished, therefore it is important to study the history of electronics, science and technology.
