The document discusses diodes, including their history and components. It describes how a diode is constructed from a P-type and N-type semiconductor material, forming a PN junction. At the junction, electrons diffuse into holes, creating a depletion region that acts as an insulator under reverse bias but allows current to flow under forward bias. The document outlines diode applications such as rectification in power supplies and their characteristic I-V curve.

A Diode is a semiconductor device with two terminals, typically allowing the flow of current in one direction only.
a thermionic valve having two electrodes (an anode and a cathode).
The three terminals of the FET are known as Gate, Drain, and Source.
It is a voltage controlled device, where the input voltage controls by the output current.
In FET current used to flow between the drain and the source terminal. And this current can be controlled by applying the voltage between the gate and the source terminal.
So this applied voltage generate the electric field within the device and by controlling these electric field we can control the flow of current through the device.
The metal–oxide–semiconductor field-effect transistor (MOSFET, MOS-FET, or MOS FET) is a type of field-effect transistor (FET). It has an insulated gate, whose voltage determines the conductivity of the device. This ability to change conductivity with the amount of applied voltage can be used for amplifying or switching electronic signals. Although FET is sometimes used when referring to MOSFET devices, other types of field-effect transistors also exist.

The Roman Empire A Historical Colossus.pdfkaushalkr1407
The Roman Empire, a vast and enduring power, stands as one of history's most remarkable civilizations, leaving an indelible imprint on the world. It emerged from the Roman Republic, transitioning into an imperial powerhouse under the leadership of Augustus Caesar in 27 BCE. This transformation marked the beginning of an era defined by unprecedented territorial expansion, architectural marvels, and profound cultural influence.
The empire's roots lie in the city of Rome, founded, according to legend, by Romulus in 753 BCE. Over centuries, Rome evolved from a small settlement to a formidable republic, characterized by a complex political system with elected officials and checks on power. However, internal strife, class conflicts, and military ambitions paved the way for the end of the Republic. Julius Caesar’s dictatorship and subsequent assassination in 44 BCE created a power vacuum, leading to a civil war. Octavian, later Augustus, emerged victorious, heralding the Roman Empire’s birth.
Under Augustus, the empire experienced the Pax Romana, a 200-year period of relative peace and stability. Augustus reformed the military, established efficient administrative systems, and initiated grand construction projects. The empire's borders expanded, encompassing territories from Britain to Egypt and from Spain to the Euphrates. Roman legions, renowned for their discipline and engineering prowess, secured and maintained these vast territories, building roads, fortifications, and cities that facilitated control and integration.
The Roman Empire’s society was hierarchical, with a rigid class system. At the top were the patricians, wealthy elites who held significant political power. Below them were the plebeians, free citizens with limited political influence, and the vast numbers of slaves who formed the backbone of the economy. The family unit was central, governed by the paterfamilias, the male head who held absolute authority.
Culturally, the Romans were eclectic, absorbing and adapting elements from the civilizations they encountered, particularly the Greeks. Roman art, literature, and philosophy reflected this synthesis, creating a rich cultural tapestry. Latin, the Roman language, became the lingua franca of the Western world, influencing numerous modern languages.
Roman architecture and engineering achievements were monumental. They perfected the arch, vault, and dome, constructing enduring structures like the Colosseum, Pantheon, and aqueducts. These engineering marvels not only showcased Roman ingenuity but also served practical purposes, from public entertainment to water supply.

This is a presentation by Dada Robert in a Your Skill Boost masterclass organised by the Excellence Foundation for South Sudan (EFSS) on Saturday, the 25th and Sunday, the 26th of May 2024.
He discussed the concept of quality improvement, emphasizing its applicability to various aspects of life, including personal, project, and program improvements. He defined quality as doing the right thing at the right time in the right way to achieve the best possible results and discussed the concept of the "gap" between what we know and what we do, and how this gap represents the areas we need to improve. He explained the scientific approach to quality improvement, which involves systematic performance analysis, testing and learning, and implementing change ideas. He also highlighted the importance of client focus and a team approach to quality improvement.
2. Invented in 1904 by John Ambrose Fleming.
Was constructed with 2 electrodes in the form of a
vacuum tube.
In 1906, Lee Dee Forest added a 3rd electrode called a
control grid and the triode, which is used as amplifier,
switch..
The application of triode created a new era in
broadcasting with the invention of the crystal radio sensor
by Pickard, 1912.
Commonly used in DC power supply units as a rectifiers
and voltage regulators, clipper, clamper circuit.
Comes in different shape and sizes
3.
4. Made from a combination of 2 extrinsic semiconductors, P-type ad
N-type material.
The joint between the P-type and N-type material is called PN
junction.
Have 2 terminal( anode and cathode).
Produced from the silicon wafer
6. Near the PN junction the electrons diffuse into the vacant holes in the P material causing a
depletion zone.This depletion zone acts like an insulator preventing other free electrons in the
N-type silicon and holes in the P-type silicon from combining.
In addition this leaves a small electrical imbalance inside the crystal. Since the N region is
missing some electrons it has obtained a positive charge. And the extra electrons that filled the
holes in the P region, have given it a negative charge. Unfortunately one cannot generate
power from this electrical imbalance. However the stage is set to see how the PN junction
functions as a diode.
7. .
At the p-n junction, electrons from the n-type
semiconductor will be attracted to the holes in the p-type
semiconductor.
As a result, the holes and the electrons at the p-n
junction disappear, forming a layer called “depletion
layer”.
At the same time, the p-type semiconductor becomes
more negative whereas the n-type semiconductor
becomes more positive.
This will result a potential difference across the p-n
junction. This potential difference is called the junction
voltage (or the barrier voltage).
The junction voltage will prevent the charge carrier from
flowing across the depletion layer.
10. The polarity of applied voltage which causes
charge to flow through the diode is
called Forward Bias. (all current, almost no
volts)
The polarity of applied voltage which can't
produce any current is called Reverse Bias.(all
volts, almost no current)
13. Forward region: It is the operation region at which the
potential applied to anode is more positive than that
applied to the cathode.
Reverse Region: It is the operation region at which anode
potential is more negative than cathode potential.
Saturation Region: Part of the reverse region where the
diode impedance is very high, and causes very small drift
current.
14. Break Down Region:The part of the reverse region
where the diode impedance is very low, and the
current passing through the diode is very high.
ThresholdVoltageVT: It is also called the knee
region. It can be determined on the I-V curve by
the point at which diode starts to conduct current
easily. It is also called the diode
barrier potential and is very near in amplitude to
the diode build-in voltage.
15. Saturation Current: it is a very small current due to
drift current in the diode in the reverse bias region.
This current is very low (in the nano-amperes range)
due to the high impedance of the depletion region.
Break DownVoltage: It is the maximum allowable
voltage in the reverse bias region, at which diode
resistance changed abruptly from very high
impedance to very low impedance. If the reverse
voltage applied on the diode exceeds this limit, a very
high current in the reverse direction passes through
the diode causing in burning it.
38. Can produce ripple voltage during both positive
and negative input cycle.
There are 2 types of full wave rectifier:
I. Two diodes full wave rectifier
II. Bridge rectifier
60. Circuit that converts the pulsating AC voltage to
a DC voltage.
The main function of filter is to reduce the ripple
in the input waveform.
Capacitor filter is very popular because of its low
cost, small size, light weight and good
characteristics
