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 Aacoil 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 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.

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. In this section we learn about
Electronics History from 1745 – 1996 and some
of the great inventions by some greatest inventions and scientists of all
times:

 PCB (Printed Circuit Board)
:
Designing, Manufacturing and Assembly:
A PCB (printed circuit board) or PC board is a piece of phenolic or glass-epoxy board with copper clad on one or
both sides.
It
is also sometimes referred to as printed wiring board
(PWB) or etched wiring board. A PCB assembled
with electronic components is called printed circuit
assembly (PCA), OR printed circuit board
assembly (PCBA). Here we learn about
Printed circuit assembly,

Electronic Circuits - Basic Circuit
Design and Schematic:
A
Electronic Circuit may be defined as a collection of electronic elements
that performs a prescribed function. An
electronic circuit is an electrical circuit that also
contains active electronic devices such as transistors or
vacuum tubes. An electric
circuit having at least one component that manipulates the
voltage or current in the circuit. Electronic circuits are categorized as analog circuits ,
discrete circuits , or mixed-signal electronic circuit (a
combination of analog and discrete). Now, let us understand
each of these:
Analog circuits ,
Series and Parallel Circuit,
Discrete circuits,
Mixed-signal circuits,
Electronic Circuits Symbols.

Electronic components
are basic electronic element or electronic parts
usually packaged in a discrete form with two or more
connecting leads or metallic pads.
Electronic Components are
intended to be connected together, usually by soldering to a
printed circuit board (PCB), to create an electronic circuit
with a particular function (for example an amplifier, radio
receiver, oscillator, wireless).
Some of the main Electronic
Components are: resistor, capacitor, transistor, diode,
operational amplifier, resistor array, logic gate etc. Here
