The diode being tested receives a reverse voltage of about 2.5V (1.9V from the LED plus 0.6V from the series diode) which is insufficient to cause damage. If the diode being tested was short ...

They might both be LCDs, but there is one key difference between the two technologies that can help deliver a better picture.

A light emitting diode (LED) emits light as electrical current passes through it. LEDs are very small, consumes less electric power and can emit lights of different colors based on the ...

Discover the science behind diodes — the tiny components that control the flow of electricity. Learn how they let current ...

American Shuji Nakamura, and Isamu Akasaki and Hiroshi Amano of Japan, will share the prize for co-developing a blue light-emitting diode that triggered a revolution in lighting technology.
