Physics? That's where you find new insights on things people have been thinking about for a long time. If you don't have two or three separate approaches to explaining something, then you don't really understand it. OK, everything we know is wrong, and transistors aren't really "current...
Amplifiers boost the power of audio signals using transistors, which are made from semiconductors like silicon that have been modified through a process called doping. The transistor in an amplifier typically involves a three-layer structure with p-type and n-type semiconductors, allowing it to cont...
Next, two very thin copper wires are twined together to make one long strand. This wire is coiled around the phosphor-coated, copper core. You now have a layered unit. You can think of its core as a sandwich -- two conductors with electricity following through them provide the energy need...
Speakers tend to be built into "enclosures" (as engineers call them—the rest of us call them "boxes") to amplify their sounds and keep them safe from damage. If you look closely, you'll see speaker enclosures usually have openings at the front or the back so air can move more freely...
Full home-automation systems let you use one remote control to manage lighting, alarm systems and entertainment components by way of a receiver wired directly into your home's electrical wiring. Chances are it won't be long before you have a single remote control to manage every electronic ...
Learn how to make simple boost converter circuits using transistors, and IC 555. These step up circuits will convert 1.5 V 3 V to 12 V, 24 V.
Computer technology advances at a faster rate than many other technologies.Computerstend to double in power every two years or so. This trend is related to Moore's Law, which states that transistors double in power every 18 months. Vinge says that at this rate, it's only a matter of time...
But unlike hard drives, which contain spinning platters and turntable-like arms bearing read-write heads, flash-memory devices have no mechanical parts. They're built from transistors and other components you'd find on a computer chip. As a result, they enjoy a label — solid state — reserv...
Transistors, resistors and diodes could be manufactured together on silicon "chips." This discovery gave rise to SSI (small scale integration) ICs. An SSI IC typically consists of a 3-mm-square chip of silicon on which perhaps 20 transistors and various other components have been etched. A ...
It was the development of transistors that spurred on the computer revolution from the mid-20th century onward. But without relays, there would have been no transistors, so relays—and pioneers like Joseph Henry—deserve some of the credit too!
