Ohmulator is a simple, yet robust, electric circuit calculator that enables you to quickly find the unknown variables of a circuit. Ohmulator allows you to easily adjust unit types on the fly (eg. milli Amps, Amps, kilo Amps), which means no prior conversion! Enter two known variables (from: I = Current, R = Resistance, V = Voltage, P = Power), set preferred units, then Ohmulator will calculate and return the previously unknown values. Also an effective (total) resistance calculator. What two App Store reviewers had to say about Ohmulator: "Great. Does what it says. Very good app. Stylish design." 5 Stars - Jamie1990jamie "Awesome app. It simply works. A must have for the radioamateur or electronic nerd. Nice to have the watt law as well." 5 Stars - Per67 Also available for macOS on the Mac App Store. ## Ohmulator Screenshots - [Screenshot 1](https://is1-ssl.mzstatic.com/image/thumb/Purple123/v4/22/38/5e/22385ec4-1a4b-efb5-2547-5659f01c1da9/mzl.dfvjcvbh.png/640x920.png) - [Screenshot 2](https://is1-ssl.mzstatic.com/image/thumb/Purple123/v4/9e/bf/47/9ebf47da-64b3-d836-a92b-0138c87fff5d/mzl.kslxxmjx.png/640x920.png) - [Screenshot 3](https://is1-ssl.mzstatic.com/image/thumb/Purple113/v4/76/71/56/7671565e-6e30-01c3-47dd-fc2da5a05d87/mzl.recvrazf.png/640x920.png) ## Ohmulator Rating Breakdown in United States - 5 stars: 61 (80%) - 4 stars: 10 (13%) - 3 stars: 4 (5%) - 2 stars: 0 (0%) - 1 stars: 1 (1%) ## Ohmulator Reviews in United States ### ***** "The Best" Great app while in school for HVAC -- kennyrocket, 2018-01-15 ### ****- "Works excellent" Could use way more algorithms though. -- El Nerdo Degeek, 2017-08-24 ### ***** "Works great, easy to use." Ohmulator does everything I need it to. I mostly use it for calculating power and current on my coil builds. Helps me ensure my mod doesn't turn into a pipe bomb! -- Jesse Coulter, 2015-01-19 ### **--- "Hate the update" Was a five star app, new update painful to look at and less functional. Will look for a replacement. Would pay for a legacy version liked to old one so much. -- Promma, 2014-04-16 ### ***** "Great update!" Thank you for the update. Very nice. -- Doug Truong, 2013-11-16 ### ***** "Love the new design!" Looks really good. -- Napzero, 2013-11-15 ### ***** "Outstanding" Very clean, very simple, does what its suppose to do. -- dimeiz, 2012-08-15 ### ***** "Slick!" Does exactly what it needs to do! -- Twisted Pair!, 2012-06-15 ### ***** "Great app" Simple and easy to use. -- Wingnut57, 2012-03-25 ### ***** "P=IR" Nice! -- DeadAccount, 2012-01-16 ### ***** "Useful for a scatterbrain" I sometimes get backward on my formulae, so this helps me keep it straight. Thanks! -- McTroyd, 2011-08-24 ### ****- "Worth it" Im an electrician and I use it pretty frequently, no 3 phase calculations, and volt drop feature would be nice too but a handy tool no-less. -- fergusoninc, 2011-08-20 ### ***** "Great App" Great for quickly calculating total amperage of high powered lighting fixtures on a circuit. -- Jtools, 2011-04-25 ### ***** "Na" Very handy & useful, especially the variable units feature. I use it in antique radio restoration. -- TranOceanicFan, 2011-03-18 ### **--- "Missing information" No 3 phase calculations otherwise a good tool. -- Kevinmck, 2011-03-07 ### ***** "Love it." Very useful. Wish you could include a option for resistors in a parallel series circuit. Five stars use it daily at work. -- DeltaDawg01, 2011-02-25 ### ***** "1star?" P=watts. Need an electrical class much? 5 stars -- Wankerry, 2011-02-25 ### ****- "Please add" A way to calculate voltage drop across a series of resistors. Thanks! -- Mccursely, 2011-02-15 ### ***-- "Easy to use!" Simple Ohm's Law calculator. I especially like the variable input unit selection since I typically deal with low power industrial instrumentation. -- MWilden, 2011-01-15 ### ****- "Clear & Simple" For those who want to better understand simple electronics, this is a very clear way to see the relationships. -- Sea2Sea3, 2010-11-25 [View all Ohmulator reviews and detailed analytics on AppTail](https://apptail.io/account/signup?utm_campaign=ai-crawl&utm_content=reviews) ## Ohmulator Store Rankings | Chart | Country | Category | Rank | |-------|---------|----------|------| | Top Paid | Denmark | Utilities | #292 | | Top Paid | Norway | Utilities | #353 | | Top Paid | Kuwait | Utilities | #353 | | Top Paid | Sweden | Utilities | #411 | ## Ohmulator Available In -
