This virtual lab provides an excellent environment for anyone who is interested in understanding series and parallel resistors, learning how to measure voltages across resistors, current through series and parallel circuits and solving simple circuits. Features - VERY SIMPLE and EASY TO USE, with up to eight component sections. - Component sections can easily be configured from five different types. - VIRTUAL "Hands On" experience using volt and amp meters. - Resistor values can easily be changed with a picker, keypad or using randomize button. - Circuit voltage can easily be changed from 1 to 1000 volts with a picker or a keypad. - The "Basics" screen make this app unique for the simplicity and speed of seeing the effects of "Opens" (resistor component with infinite resistance) and "Shorts" (resistor component with zero resistance). - FREE and NO ADVERTISEMENTS. - The circuit is always "LIVE" and immediately shows voltage, current and circuit resistance with any changes made to the circuit. ## Simple Circuit Builder Screenshots - [Screenshot 1](https://is1-ssl.mzstatic.com/image/thumb/PurpleSource211/v4/c1/45/d8/c145d8b3-f645-d0d4-74d2-6474b5dbf3bf/5a9bdd41-3f50-4b90-97b4-35d7d7dd6e75_iPad_1A.png/2732x2048.png) - [Screenshot 2](https://is1-ssl.mzstatic.com/image/thumb/PurpleSource211/v4/c1/b4/6f/c1b46f51-efa9-5520-7572-d3eaa4aca7de/d0fdce6a-970d-4c2e-b856-107afc0679d0_iPad_3.png/2732x2048.png) - [Screenshot 3](https://is1-ssl.mzstatic.com/image/thumb/PurpleSource211/v4/c7/07/a2/c707a249-8c3b-e291-c8ca-d2f180e40422/0383ac64-1748-4d43-90f5-0c19ab416e3c_iPad_2.png/2732x2048.png) - [Screenshot 4](https://is1-ssl.mzstatic.com/image/thumb/PurpleSource211/v4/ef/fc/f6/effcf64c-c8f5-7987-70b4-e1237c6f15df/e2e53714-863f-499a-b5ca-8d338583d75c_iPad_4.png/2732x2048.png) - [Screenshot 5](https://is1-ssl.mzstatic.com/image/thumb/PurpleSource211/v4/2a/00/97/2a0097a6-fdcb-5782-5005-78490d7a7601/63fc08d7-848a-4123-945f-96577870e4e9_iPad_5.png/2732x2048.png) ## Simple Circuit Builder Rating Breakdown in United States - 5 stars: 18 (64%) - 4 stars: 2 (7%) - 3 stars: 2 (7%) - 2 stars: 1 (4%) - 1 stars: 5 (18%) ## Simple Circuit Builder Reviews in United States ### ***-- "Please add" Please add unbalanced circuits/branching. Otherwise it's just an Ohm's law calculator. See PHET for amazing implementation. Also I HAD to download it to see the prayer. I thought the other reviewer was being a baby, so I had to see. I'm not offended, but I don't get it. Like... was this done at church camp? Did the church let you use the computer? Was your electronics teacher a Christian? Was faith the only thing that kept you going to finish the app because no one else did? Clarify plz, testify if you will. -- この猫は, 2024-03-14 ### ***** "AWESOME APP" Hey ive never written a review ever, but your app is awesome and I love it so mucH. I love tHat you added a christian secrion wHere one can become connected to God. All glory to tHe almighty king of tHe heavens. If you put God before everything tHat you do, if you incorporate him in your everyday life, no matter wHat it is tHat you will do, you will succeed. Not many will understand our works devotion goes out to him, but I do, and I see your work. All glory to God. Thank you for creating sucH a helpful app! its really Helping me get through finals! -- Isaiguevara, 2020-12-15 ### *---- "app not suitable for minors" To your cheap and hypocritical answer I know that you do with the app whatever you want, but please do not invite minors as it indicates that the app can be used from four years onwards. -- ejoeldwin, 2020-11-16 ### ***** "Nice app" It’s a nice app for tinkering & learning electrical circuits. I’m happy with it. It’s kinda funny, seen several reviews chastising the creator of this app for having a preyer or statement of the Christian faith in the app, when they can clearly choose not see it. It’s most likely the same type people who preach themselves about tolerance and understanding of different cultures & religions. As a proud deist & true believer in equality for all, this doesn’t bother me at all. Y’all should stop the hate & learn actual tolerance for others beliefs. It’s that simple. No attempt at conversion here, just a scripture. Some need to learn the definitions of words they use before spouting off in anger & disagreement. If true equality bothers you, delete the app & move on or create your own with whatever you want in it. Let the creator do what he wishes with the apps they create. Simple as that. -- Jt8018, 2020-02-09 ### ***** "I think it’s super rad" Hey that’s super rad that you have a rededication prayer on this app! Didn’t expect it! That’s truly inspiring, and I thank you for that! Jared B -- Jazzmaster4jesus, 2020-01-14 ### ***** "Thanks a lot!!!" Excelent app, for validate ohms law calculations, God bless!!! -- Xeekder, 2019-11-29 ### ****- "Huh?" Why is there a Christian prayer in an app for simple electric circuits? Hey, I appreciate that you asked if I would be offended to click cancel, but seriously. I appreciate your religion, really I do, but maybe write another app for that -- Vodakas, 2019-08-17 ### *---- "Really" Why do you have to try and convert people to Christianity. I would have enjoyed using this app but because of prayer button I’m deleting in. I don’t use apps that try to convert me. -- Brilldude, 2019-03-08 ### ****- "Voltage Drop?" I am not seeing voltage drop across a resistor? I would think I should. -- DT466, 2019-03-07 ### ***** "Easy to understand app" David, Thanks for the app! It’s just what I was looking for in a simple, no flash, over programmed app. The prayers were appreciated too... -- wadefallin, 2018-11-12 [View all Simple Circuit Builder reviews and detailed analytics on AppTail](https://app.apptail.io/signup?utm_campaign=ai-crawl&utm_content=reviews) ## Simple Circuit Builder Discovered Keywords -
