It requires two external resistors to adjust the output voltage. The recommended value for R1 is 240Ω but it can also be some other value between 100Ω to 1000Ω. So you need to enter a value of R2 in ...

This circuit is very useful for all analog circuits where variable voltages are required, hence it is important to understand how this circuit works and how to calculate the values of Resistors. A ...

The Resistor Color Code Calculator is a tool designed to compute resistance values from color bands. With a responsive interface and integrated Progressive Web App (PWA) support.

To calculate the resistance of the series resistor required, we need to look at the current and voltage values recommended by the LED manufacturer. Suppose a manufacturer recommends a maximum ...

You can specify your collection of standard resistors in the URL and bookmark it. Here is an example URL The voltage divider tool allows easy calculations of voltage dividers. You have to enter three ...

When resistors are connected in series, the total of all the voltages (sometimes referred to as potential difference) across each component is equal to the voltage across the power supply.

Resistances in parallel is a common term used in industrial, commercial, and institutional power systems. Therefore, a good understanding of working with resistors in parallel and calculating their ...
