ElectraLab is a browser-based electricity simulator for vocational (FP) students. Build circuits, take measurements and practice finding faults before you get to the workshop. Once you find a fault, the AI explains it. Nothing needs to be installed.
Pricing: try it free, no installation. The page is primarily in Spanish, with English as an alternate locale.
Vocational schools need hands-on electronics practice without depending on physical labs or installing software, so we built a lab that runs in any browser.
