Pull one wire: 0.0 mA, dark. Put it back: 21.2 mA, lit. And with no resistor at
all, the LED burns out on the spot ⚡

Two switches in series. One on: dark. The other on: dark. Both on: it lights.
That's an AND gate ⚡

220 Ω and the LED burns out. 330 Ω and it lives. Then tune it all the way to
4700 Ω, straight off the meter ⚡

24/09/2026

Two 330 Ω branches. Close the switch and the meter reads 165 Ω, not 660.
More paths, less resistance ⚡

9 V in, three LEDs in series. Where does it go? 3 + 2 + 2 + 2, straight off
the meter. Pull one LED and they all go dark ⚡

A circuit is not a pile of parts — it is a loop. Open it anywhere and the lamp stays dark. Built live on a phone, nothing cut 💡
