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.
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. See more »
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 chemicals?
