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 ...

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 ...

[mircemk] built a slick-looking LED tester with a couple handy functions built in. Not only can one select a target current to put through an LED, but by providing a target voltage, the system will ...

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.

The Resistor Calculator program was developed to calculate the ResistorValue, once you input the values for the following; supply voltage, forward voltage and lastly the rated current you would be ...

The project is originally designed as LED calculator but the addition of a rotary encoder to set the target system voltage results to adjusting the LED brightness using the potentiometer. By turning ...

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, it is essential to understand how to calculate the voltage across various components, such as resistors. In this article, we will explore the methods for ...

The ballast calculator is designed to help AV technicians build large LED video walls safely, even when official stacking systems are used, but can never replace a structural calculation. ROE Visual ...

In an electrical circuit, voltage is the force that pushes the electric current through the various components. When current passes through a resistor, some of the voltage gets used up or “dropped” ...
