OhmEE is a simple, clean, and easy-to-use resistor color code calculator. Simply set the picker wheels to the color bands on any resistor and the resistance, tolerance value, and maximum and minimum tolerance values are calculated and displayed. 5 and 6 band resistors now implemented as well as a feature to calculate the color bands for a given resistance. Also added an Ohm's Law calculator. ## Key features - Resistor color code calculation - 5 and 6 band resistor support - Calculate color bands for given resistance - Ohm's Law calculator - Simple and clean interface ## Is OhmEE safe?

Works well and I really like it. ### 4/5 — Very Nice! *2011-03-18* This is a very useful app. If possible, I would like to see 'power' added to the ohm's law calculator. ### 5/5 — Versatile! *2011-03-08* First free resistor APP I found with support for other than only 4-band resistors. ### 5/5 — Full featured, free *2011-02-12* One other app only looked up resistors unless you paid. ### 4/5 — Useful tool *2011-01-21* Good free app. Nothing too fancy but works like it says. No complaints. ### 5/5 — Absolutly great! *2010-09-30* This app is great for the price. Most other apps charge you to get codes for 5 and 6 bands. This one does it for free. It also allows you to input a value and it spits out the color code. Very stable. ### 1/5 — bleh *2010-08-19* bleh this app could be better, it seems to work but just looks pretty crappy. not fun to use, there's prettier apps out there that do the same thing. ### 4/5 — Nice *2010-04-16* It does what it says on the box. Now just make a version that does cap codes too and I'd happily pay for it. :D ### 5/5 — Super rad! *2010-03-30* I was surprised to find not only an intuitive resistor calc, but also both a reverse lookup as well as an ohm's law calculator. Just what I was looking for! Thanks! ### 5/5 — Best free resistor identifier! *2010-03-22* I am a picky person when it comes to programs that could make or break something of myne. This app is accurate, very user-friendly and fast. If you need to identify a resistor, whether uts 4,5, or 6 bands, this is the perfect app. I'm Wolfie Darkpaw, and I support this app ## Frequently asked questions about OhmEE ### What is OhmEE?
