A diode is a tiny component with a powerful job—controlling the direction of electrical current. This video explains how ...

Electricity doesn’t just flow freely in every direction—it needs control. That control comes from a tiny but powerful component: the diode. In this video, you’ll learn how diodes work, why they allow ...

A semiconductor-based laser used to generate analog signals or digital pulses for transmission through optical fibers. Both laser diodes and LEDs (light-emitting diodes) are used for this purpose, but ...
