As an example, with a 12-V input, using a 2.5-V Zener diode would require a 1.9-kΩ series resistor to maintain 5 mA (assuming no load current).

I use simpler method. Connect laser diode to 5 V supply and 470 Ohm resistor. No lasing – go lower with resistance, to 390 Ohms. No lasing, go lower to 330 Ohms, etc … until lasing starts.

AND gate implemented as diode-resistor logic. (Credit: Anthony Francis-Jones) The fun part about logic gates is that there are so many ways to make them, with each approach having its own ...

You can build a simple low-current voltage regulator from a resistor and a Zener diode. This type of regulator is often adequate for noncritical applications such as internal bias voltages. The ...

But most any full scale current can be selected by choosing a suitable resistor. Voltage Vs developed by Rs is sampled by series connected LEDs of optocouplers O1 and O2 according to a variant of the ...

Flexible organic memory devices are promising candidates for data storage applications. Here, Ji et al.develop a flexible all-organic 64-bit memory cell array possessing one diode–one resistor ...

By putting in a 6.8-Ω resistor, Pease caused the current through the LED to be 10 mA. 1. Bob Pease used an LM334 current source to servo the current from a PNP transistor through an LED diode.
