Many LEDs, those highly popular Light Emitting Diodes, die prematurely because they are improperly used by people who know little to nothing about electronics. Let's try to stop the massacre. An LED ...

Knowing how to calculate an LED current limiting resistor is one thing, taking into account all other sorts of parameters as well is another. In Part 1 you learned how to calculate a current limiting ...

Every LED has its own characteristics and specifications, depending on the materials used to make them, their colour and many other parameters. As we know the LEDs have a forward voltage, just like ...

Time will always be“of the essence” for professional engineers and amateur enthusiasts alike. This can certainly be said about the process of designing circuits involving Light Emitting Diodes (LEDs).

It seems LED's are everywhere. So here is a calculator to figure the resistor value for you. As usual, I've taken a simple formula and made it really complicated. Hope you find it helpful.

Below this section, all the resistors in E series and Renard’s numbers compatible to the entered value are listed. The closest match given in this set would be highlighted with green font. In the ...

Every resistor is marked with colour bands that indicate its resistance, tolerance and sometimes temperature coefficient as well. You might be familiar with the mnemonics for memorising the resistor ...

When working with electrical circuits, one of the most fundamental concepts to understand is how to calculate the voltage drop across a resistor. Voltage drop refers to the decrease in voltage as it ...
