Solid State Components are the building blocks of today's technology. From batteries and circuit breakers to oscillators and microcontrollers, they make up the gadgets and machines that we use every day.
- Quiz Yourself: Batteries
You can find batteries under the hood of your car, inside a TV remote -- even within hearing aids. Batteries were invented nearly two centuries ago, and they keep getting more sophisticated. But how well do you know what's at work inside these cans of che
- Quiz Yourself: Electric Motors
Electric motors are inside all kinds of ordinary devices, using a power source to make motion. So what makes the motor go 'round?
- How Batteries Work
Batteries power all sorts of things -- they're in our cars, our PCs, our cameras, our cell phones. How do these tiny cans of chemicals provide power for so many of our daily conveniences?
- How Capacitators Work
The capacitor plays a crucial role in electronics -- it stores electrons for when they're needed most, dumping a huge charge instead of a steady flow.How does it do it?
- How Circuit Breakers Work
The circuit breaker is one of the most important safety mechanisms in your home. Without it, the risk of fire would skyrocket. Learn how a circuit breaker keeps your home's electricity in check.
- How Electric Motors Work
You might be surprised to find out just how much work is done by electric motors. They're everywhere! You'll find them in your car, your kitchen, bathroom, office... Find out how electric motors get stuff moving.
- How Flash Memory Works
Flash memory is the essential component in solid-state hard disks and digital cameras. It retains data even when the power source is disconnected. Without it, you’d have to reload your data each time you shut down. Learn all about the memory that never
- How Inductors Work
An inductor is little more than a coil of wire. Sound simple? Well, it is -- but that coil of wire can do some pretty cool things. Learn all about inductors and what they're used for in our article.
- How LCDs Work
Liquid crystal displays are found in everything from digital watches to laptop computers. In a relatively short period of time, they've crept from a fascinating novelty item to a technology standard.
- How Light Emitting Diodes Work
Light emitting diodes form the numbers on digital clocks, send data from remote controls, light up traffic signals, illuminate watches -- the simple genius of the design makes it infinitely applicable. Find out how this thing called a "diode" produces lig
- How Lithium-ion Batteries Work
Lithium-ion batteries are incredibly popular these days. You can find them in laptops, PDAs, cell phones and iPods. Find out why.
- How Oscillators Work
Oscillators show up in lots of electronic equipment. In fact, you might be surprised to know that computers, radios, metal detectors and stun guns all use oscillators. Learn all about electronic oscillators.
- How Semiconductors Work
Semiconductors form the heart of modern electronics. Learn about semiconductors, silicon, doping, diodes and other fascinating technologies.
- How Wireless Power Works
Unless you're particularly organized and good with those little twist ties, you probably have a few dusty power cord tangles around your home. But wireless power transmission could soon cut the clutter and lead to clean sources of electricity.
