OhmQuest: Circuit Lab

OhmQuest turns abstract middle-school electricity into interactive buildable, runnable, observable simulation labs for students, parent-child study and electronics fans. 100 progressive challenge levels let you build circuits and observe phenomena to master current, voltage, resistance, heat and electromagnetism. 200 exam exercises require real circuit operation before answering, stopping rote memorization. Free sandbox mode with power supplies, meters, motors and electromagnetic parts. Adjust parameters and view formulas instantly to recreate textbook circuits anytime. No account, no ads, no data tracking; all progress saves locally. For educational use only, not professional electrical engineering. Subject to Apple’s Standard EULA.
