Most semiconductors are made of a poor conductor that has had impurities (atoms of another material) added to it. The process of adding impurities is called doping. In the case of LEDs, the conductor material is
Aluminum base PCBs – Mainly used in lighting equipment. Since super-bright LEDs generate a lot of heat, it is necessary to dissipate it as quickly as possible in order to increase their service life and prevent overheating. There are also technologies that allow you to solder directly onto an...
In microwave cooking, the radio waves penetrate the food and excite water and fat molecules pretty much evenly throughout the food. No heat has to migrate toward the interior by conduction. There's heat everywhere all at once because the molecules are all excited together. There are limits, ...
At one time or another, we've all been told not to use metal products, especially aluminum foil, when cooking with a microwave oven. Stories of incredible explosions and fires usually surround these ominous warnings. Why is that? Let's take a look at how microwave ovens work to find out...
“But in semiconductors, they’re close enough so that, when a heat source is applied, electrons can jump from the valence band to the conduction band, enabling the flow of electric current.”Determining the strength of that current is up to the amount of voltage applied, as well as the ...
Find the tap you need (3/8"-24 in my case) and the drill you need (make sure to look it up in a table!). This should be pretty straightforward: drill the holes in the same location as you did on the top side. As before, make sure you start with a center drill!
The currents must find a return path and ground is dedicated for that. So, separate ground does not mean having two different grounds, but they must be common. In the case of a multilayer board and separate ground between digital and analog, ...
to seemed to think like I did at first in regards to people literally talking down the shaft where there was an opening in a different department. Then the voices came through the walls and when I didn't find a plausible source that was easily correctable... more than issues from voices...
Potatoes seem pretty dry, but they contain enough moisture to permit the conduction of electrons and ions through the protein-and-starch matrix of the potato. Stick a penny and a galvanized screw into a potato, connect them to an LED, and the LED will light. Wire a thousand potato ...
The ET is made of aluminum and aluminum composite materials. It has two separate tanks inside, the forward tank for oxygen and the aft tank for hydrogen, separated by an intertank region. Each tank has baffles to dampen the motion of fluid inside. Fluid flows from each tank through a 17...
