One of the questions that hobbyists ask over and over is how to select the value of a current limiting resistor for an LED. Usually the seat of the pants response is: “Subtract 2 V from the supply ...

SOME MULTI-STRING LED MODULES come with a common-anode configuration. The commonanode connection reduces the number of wires between the LED module and its driver from 2N to N+1, where N is the number ...

Hi there, and welcome to Part 3 of this soon-to-be-heralded mega-mini-series. In Part 1, we discussed the first vacuum tube diodes, moved on to their solid-state (semiconductor) descendants, and then ...

Cathode and Anode: These terms are widely used in electrolysis and electrochemical systems. Understanding them is important, as their charges vary based on the system and reaction they are involved in ...

Infrastructure projects like the Tokyo Gate Bridge are now turning to LED lighting because of its economical and environmental advantages. But these devices still need the right current-limiting ...
