Elec Class
learn electricity hands-on
Elec Class is designed and developed by Alcala Web: websites, applications and teaching tools, from the first idea to going live. This simulator is one of its projects; the Alcala Web site presents others.
Handle to understand: build a circuit as in the lab, measure, make mistakes safely, then practise every part of a general-electricity course (basics, Ohm's law, resistor networks, real generators, Kirchhoff, measurement...). Three modes: sandbox, game by learning paths, graded practice.
The topic split and the guided-problem format (unknown, formula, units, data, result) are inspired by general-electricity courses at pre-technical-college level, including the "Électricité préparatoire" course of ISL (Liège). No statement or figure from those courses is reproduced: all content is original, written by Alcala Web. Symbols follow IEC 60617.
Everything is stored in the browser (localStorage), with no account or server: progress, coins, marks, language. Progress is tied to this browser on this device; it disappears if you clear the site data or browse privately. No usage data is sent; the contact form only sends what you type, and the technical context only if you tick the box.
