Electrons form a spinning cloud around the nucleus. Protons and neutrons make up the mass of atoms. Electrons, miniscule compared to the protons and neutrons, contribute very little to the overall mass of atoms.Atoms and Isotopes Atoms of the same element have the same number of protons. All...
How to Overclock an AMD CPU: Precision Boost Overdrive (PBO) CPU Overclocking Benchmark Results CPU Overclocking Impact on Lifespan and Reliability Motherboard BIOS Overclocking Glossary (Image credit: Intel) Do you want to know how to overclock your CPU? If so, this guide is for you,...
There are many series of Arduinos but "Arduino Start Kit" has the most simple processor(ATmega328P) and guide book ATmega328P has an 8-bit core which is a good place to start digital circuit design and firmware development. You don't need to know how to draw schematics and layouts and...
The Earth's core is iron, and we know it has a north pole and a south pole. These aren't just geographical designations but actual opposing magnetic poles. The dynamo effect, a phenomenon that creates massive electrical currents in the iron thanks to the movement of liquid iron across the...
As you know, we have seen that when current flows in a wire, a magnetic field is created around the wire. Current is simply a bunch of moving electrons, and moving electrons make a magnetic field. This is how electromagnets are made to work. This will be important to keep in mind as...
Voltage is the force of electrons wanting to move from a conductor crowded with electrons to a conductor with fewer electrons and more elbow room. Current is the measure of how many electrons are flowing through a conductor--the more electrons flowing, the higher the current. Keep this in ...

How can scientists search for strange matter if no one's ever seen it? Well, they actually do know what bits of strange matter would look like on Earth if it weren't dangerous. It would resemble our regular atoms -- a positively charged core made of quarks, with electrons around -- on...
Relays use an electromagnet to mechanically switch a circuit on or off, allowing a small amount of electrical power to control a much larger power load. Commonly found in both household appliances and vehicles, relays enable electronic controls to operate high-power circuits like motors and lights...
Matter, as you probably know, is composed of atoms. Break something down to small enough pieces and you wind up with a nucleus orbited by one or more electrons, each with a negative charge. In many materials, the electrons are tightly bound to the atoms. Wood, glass, plastic, ceramic,...
