Six hands-on labs — real formulas, real probe placement, real trade-offs. Pick one below. Nothing here is locked or ordered; explore whichever teaches what you're stuck on right now.
Pick a gauge, a run length, a load — find out if the wire runs safe, warm, or overloaded.
Volts, amps, ohms — and where the probes actually go. Get it wrong in Amps mode and you'll blow the fuse.
DC vs. AC vs. Brushless, same load — three completely different ways to lose power.
Ah, Wh, C-rate — and whether your panel can actually keep up with your load.
Why combining resistors doesn't just add them up — series, parallel, and both at once.
120/240V split-phase, 3-phase WYE and Delta, and the wild leg nobody warns you about.
tools/electric-forge/[module-id].html matching its locked moduleId (e.g. wire-lab.html). Rename on deploy if your actual paths differ. Progress strip ("N / 6 wrapped up") now reads real Session Log Entry counts for the resolved member (see script below) — still doesn't distinguish "wrapped up today" vs. "ever," and still doesn't solve the ?member= handoff gap (see note in script).
