The Most Common Basic Electronic Components

These are the most common components


  • Resistors
  • Capacitors
  • LEDs
  • Transistors
  • Inductors
  • Integrated Circuits

I didn’t understand the resistor in the beginning.
It didn’t seem to do anything! It was just there, consuming power. But with time, I learned that the resistor is actually extremely useful.
You’ll see resistors everywhere. And as the name suggests, they resist the current.
But you are probably wondering: What do I use it for?
You use the resistor to control the voltages and the currents in your circuit.By using Ohm’s law.
Let’s say you have a 9V battery and you want to turn on a Light-Emitting Diode (LED).
If you connect the battery directly to the LED, LOTS of current will flow through the LED!
Much more that the LED can handle. So the LED will become very hot and burn out after a short amount of time.
But – if you put a resistor in series with the LED, you can control how much current is going through the LED.
In this case we call it a current limiting resistor.

Meet this Computer Prodigy

London:  Setting an unprecedented record, a seven-year-old British boy of Pakistani origin has become the world's youngest computer programmer. Muhammad Hamza Shahzad, resident of Handsworth area in Birmingham has been trained by his father Asim, who works with an American IT firm.   "I want to be Bill Gates," he told 'Birmingham Mail' this week. This is not the first time when Hamza has set a world record, he had become the world's youngest Microsoft Office Professional (MOP) last year at the age of six. In an exam, where candidates needed 700 points to get the coveted certificate, Hamza has scored 757, a Microsoft spokesperson said, adding he is now proficient in Software Development Fundamentals. "He can easily create Web App and manages to develop his own basic shopping cart app," he said. "He has got his hands dirty in Windows desktop App, console App, windows services, Web services and finds it really fun to develop simp...

Next Generation Transport System

team from MIT  took top honors Saturday at a competition at Texas A&M University to design the Hyperloop, a high-speed transportation concept dreamed up by Tesla Motors and SpaceX CEO Elon Musk. Beating out a field of more than 100 other teams from around the world, the group of MIT graduate students won the best overall design award for a vehicle, or pod, that will ride inside the Hyperloop, a system of tubes connecting major cities — or what Musk calls “a fifth mode of transportation.” They will now move on to build a small-scale prototype of their design and test it this summer on a track being built next to the SpaceX headquarters in Hawthorne, California. “MIT has been involved in so many technological breakthroughs in the past century,” says team captain Philippe Kirschen, a master’s student in aeronautics and astronautics. “It just makes sense we would help advance what might be the future of transportation.” In 2013, Musk declared war on conventional inter-city...
