Imagine that you are working on your newest project and have a bunch of LEDs on your table. You need to wire those LEDs to a power source and you don't know what resistor to use, and you don't want to use long equations to find that out. Or maybe you have a bunch of resistors and need a resistor with a specific value and don't have time to test each one with a multimeter. If you find yourself in similar situations many times ElectroHelper is just for you. ElectroHelper is a must have set of tools and calculators for anyone that uses electronic components in their projects/work.


- LED resistor calculator. Works with single LEDs or multiple LEDs connected in series or parallel.

- Converts a resistor color code to the actual value - supports 4, 5 or 6 band resistors.

- Converts a resistor value to resistor color code - supports 4 and 5 band resistors.

- Inductive Reactance calculator

- Capacitive Reactance calculator

- Built in help

Somewhat correct

The help window says LEDs are typically 2v while they are actually normally 3v. Also when you calculate the need for a resistor if you have something for example like this 9v power supply and three 3v LEDs 20ma in a series it says you need no resistor which it will work without one but it is better to add a 1OHM resistor just to make shire the power won't peak and damage LEDs. That's all I found wrong so far and I will rewiew again if nessicary.
