Your son has to build an electric generator for the school science fair and he asked you to help him. Learn about how to build an electric generator in this article.

How Capacitors 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 does a brushless electric motor work?

The brushless motor is more precise than a regular electric motor and it's also a great deal more efficient. Learn all about brushless motors and how the invention of transistors led to their development.

How OLEDs Work

Imagine a TV that is 80 inches wide and less than a quarter-inch thick, consumes less power than most TVs you can buy today and can be rolled up when you're not using it. OLEDs can make it happen. Find out how.

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 Light Emitting Diodes Work

Light emitting diodes form 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.
