ELECTRICAL Vs ELECTRONICS

Often confused between electrical ,electronics study and their devices? then this post is for you.

These two studies are actually different and seems to overlap each other. Both devices works with electricity .

ELECTRICAL :

Electric energy is produced by the flow of electrons. Electrical device converts electrical energy to another form of energy as heat, light etc. It is concerned with the large-scale production and distribution of electrical power.

Examples :

1)electrical energy->  ->light energy

2)electrical energy->-> mechanical energy

Circuit mostly consist of connecting wires,switches,fuse,transformer…

ELECTRONICS:

Electronic devices has the capability of controlling the flow of electrons to do certain task, like water heater with auto cut off features etc. As they controls the flow of electricity to process information and to control systems.

COMPARISON:

Here are few differences described,

ELECTRICAL DEVICESELECTRONICS DEVICES
here current conducted threw metals like copper,aluminium.they use semiconductor material to conduct.
They use Alternating current. eg : generatoruse direct current
works on high voltage,consume more powerworks on low voltage,less power consumption
do not manipulate dataelectronic devices are used to manipulate data
large require more spacesmall compact,require less space .so used in Integrated chips.
Examples : fan,transformer,generator,motor.Examples: transistors, microcontrollers

Circuits -Basic components:

  • RESISTORS
  • CAPACITORS
  • DIODES
  • TRANSISTOR
  • INDUCTORS
  • SWITCH
  • TRANSFORMER etc….

In digital world ,we all want things to happen automatically,wish to control everything from our place within seconds. These wishes’ fulfilled by combining electrical device with electronic circuits, due to electronic circuit’s small size,control,processing capability . So it is used in most of the electrical devices,home applicants. electronics circuits used for display,remote control,auto open,close,level checker such many features in lot of home applicants,industry,etc..

Consider these cases:

  • An electric chair
  • An electronic chair

The first is a chair which predominantly features electricity. The second is a chair which has some feature made of a complex circuit (for example, the seats in cars which are automatically-adjusting).

  • An electric toaster
  • An electronic toaster

The first is a run of the mill toaster. The second is a toaster that lets you program in an image to burn into the toast, and which sends you an email when the toast is done

Electrical and electronic engineering careers and opportunities:

  • Cybersecurity consultant
  • Design engineer
  • Electrical engineer
  • Electronics field engineer
  • Energy engineering consultant
  • Nuclear controls engineer
  • Software engineer
  • System engineer
  • Technology analyst 

core subjects for electrical & electronics engineering:

  • Communication Electronics
  • Digital System Engineering
  • Electrical Circuits and Networks
  • Electronic Devices and Circuits

Electronics is a sub field of electrical engineering, so it’s safe to say something is electric when we don’t know if electronics is actually used in the design. When we say a device is electronic, this is because we know or we assume the circuit contains electronic components.

The distinction electric / electronic is not based on the purpose or the function of the circuit, e.g. dealing with power vs dealing with signal, as stated in other answers.

From all we can come to an end in one line that

ALL ELECTRONICS DEVICES ARE ELECTRICAL DEVICES BUT NOT VICE VERSA!!!

EFFECTS OF GLOBAL WARMING

Global warming is expected to have far-reaching, long-lasting and, in many cases, devastating consequences for planet Earth.

Global warming, the gradual heating of Earth’s surface, oceans and atmosphere, is caused by human activity, primarily the burning of fossil fuels that pump carbon dioxide (CO2), methane and other green house into the atmosphere.

Despite political controversy about climate change, a major report released Sept. 27, 2013, by the Intergovernmental Panel on Climate Change (IPCC) stated that scientist are more than concern of the link between human activities and global warming. More than 197 countries agree that global warming is real and has been caused by human action.

Already, global warming is having a measurable effect on the planet.

“We can observe this happening in real time in many places. Ice is melting in both polar ice caps and mountain glaciers. Lakes around the world, including Lake Superior, are warming rapidly — in some cases faster than the surrounding environment. Animals are changing migration patterns and plants are changing the dates of activity,” such as trees budding their leaves earlier in the spring and dropping them later in the fall, Josef Werne, a professor of geology and environmental science at the University of Pittsburgh, told Live Science.

Here is an in-depth look at the changes wrought by global warming.

Increase in average temperatures and temperature extremes

One of the most immediate and obvious effects of global warming is the increase in temperatures around the world. The average global temperature has increased by about 1.4 degrees Fahrenheit (0.8 degrees Celsius) over the past 100 years, according to the National Oceanic and Atmospheric Administration (NOAA).

Since record keeping began in 1895, the hottest year on record worldwide was 2016, according to NOA AND NASA. That year Earth’s surface temperature was 1.78 degrees F (0.99 degrees C) warmer than the average across the entire 20th century. Before 2016, 2015 was the warmest year on record, globally. And before 2015? Yep, 2014. In fact, 16 of the 17 warmest years on record have happened since 2001, according to NASA.

IRON DOME THE SHIELD OF ISRAEL

IRON DOME PROTECTING ISRAEL LIKE WAKANDA-

Iron Dome is an effective, truck-towed, multi-mission mobile air defence system developed by Rafael Advanced Defence Systems. The system has been developed to counter very short-range rockets and 155mm artillery shell threats with ranges of up to 70km. It can be operated in all weather conditions including fog, dust storm, low clouds and rain.

The all-weather air defence system protects the population and critical assets and can be strategically placed to reduce collateral damage. Iron Dome detects, analyses and intercepts a range of incoming threats, including C-RAM, precise guided missiles, cruise missiles, unmanned aerial vehicles and air-breathing threats.

The system has so far intercepted more than 2,500 incoming targets with a success rate of over 90%.

Selected by the Israel Defence Ministry, Iron Dome provides defence against short-range missiles and rockets which pose a threat to the civilian population of Israel’s northern and southern border.

“In July 2010, the US House of Representatives approved $205m in funding to speed up the production and deployment of Iron Dome.”

The system was deployed by the Israeli Air Force (IAF) in March 2011.

In November 2012, Israel installed the fifth Iron Dome battery at Gush Dan in response to the rocket attacks on the Tel Aviv area. The Iron Dome air defence system is being used to intercept and shoot down hundreds of rockets from Gaza as the latest round of escalations between Israel and Palestine in May 2021 engulfed the region. The violent clashes saw Hamas launch a barrage of rockets targeting Tel Aviv in Israel in response to an alleged Israeli airstrike in Gaza. The death toll in the Gaza Strip as a result of the Israeli airstrikes stood at more than 60 people.

I-DOME is a mobile version of the system, which can be deployed on a single truck, while C-DOME is a naval version.

Iron Dome mobile air defence system background and development details

The firing of rockets by Hezbollah during 2006’s Second Lebanon War led to the development of Iron Dome. Nearly 4,000 rockets, mostly of the short-range Katyusha type, were fired on Haifa and other northern regions of Israel.

About 44 Israeli civilians were killed in the attack and approximately 250,000 citizens were evacuated and relocated to other parts of Israel.

Between 2000 and 2008, more than 4,000 mortars and 4,000 rockets (mostly Qassams) were fired from Gaza into southern Israel. As the range of the Qassam has been expanded due to the introduction of 122mm Grad launchers, nearly one million southern Israelis came within the range.

To counter the rocket threats, the Israel Defence Ministry decided in February 2007 to develop a mobile air defence system.

The missile defence system was successfully tested in March 2009. The testing was carried out without physically intercepting a missile or rocket. In July 2009, during a defence ministry test, the system successfully intercepted a number of rockets.

A new battalion was established by the IAF in August 2009 to operate the Iron Dome system. Multiple rocket bombardments mimicking Qassams and Katyushas were intercepted successfully in a test carried out in January 2010.

The final testing of the Iron Dome was undertaken in July 2010. The system successfully determined and intercepted only incoming missile threats, while other missiles which were headed toward open fields were not intercepted.

Raytheon collaborated with Rafael for the commercialisation of the Iron Dome weapon system in the US in August 2011. Raytheon secured a $149m contract from Rafael for the supply of Tamir interceptor components used in the system, in September 2014. It was formed as a new joint venture between Raytheon and Rafael in August 2020 to establish an Iron Dome production facility in the US.

The heart of Nintendo’s new console isn’t the Switch


A wonderful serenity has taken possession of my entire soul, like these sweet mornings of spring which I enjoy with my whole heart.

I am so happy, my dear friend, so absorbed in the exquisite sense of mere tranquil existence, that I neglect my talents.

I am alone, and feel the charm of existence in this spot, which was created for the bliss of souls like mine. I am so happy, my dear friend, so absorbed in the exquisite sense of mere tranquil existence, that I neglect my talents.

I should be incapable of drawing a single stroke at the present moment; and yet I feel that I never was a greater artist than now.

When, while the lovely valley teems with vapour around me, and the meridian sun strikes the upper surface of the impenetrable foliage of my trees, and but a few stray gleams steal into the inner sanctuary, I throw myself down among the tall grass by the trickling stream; and, as I lie close to the earth, a thousand unknown plants are noticed by me: when I hear the buzz of the little world among the stalks, and grow familiar with the countless indescribable forms of the insects and flies, then I feel the presence of the Almighty, who formed us in his own image, and the breath of that universal love which bears and sustains us, as it floats around us in an eternity of bliss; and then, my friend, when darkness overspreads my eyes, and heaven and earth seem to dwell in my soul and absorb its power, like the form of a beloved mistress, then I often think with longing, Oh, would I could describe these conceptions, could impress upon paper all that is living so full and warm within me, that it might be the mirror of my soul, as my soul is the mirror of the infinite God!

O my friend — but it is too much for my strength — I sink under the weight of the splendour of these visions! A wonderful serenity has taken possession of my entire soul, like these sweet mornings of spring which I enjoy with my whole heart. I am alone, and feel the charm of existence in this spot, which was created for the bliss of souls like mine.Paragraph
