Schematic reader
Learn to read circuit diagrams like a bench tech.
Tap symbols, trace current paths, identify test points, and connect simplified schematics to real low-voltage measurements.
Safety first, always.
ElectroLab AI teaches theory, low-voltage electronics, and planning concepts. Mains voltage, switchboards, fixed wiring, high-current systems, and legal electrical work must only be performed by licensed electricians where required.

Bench next move
Calculate the LED resistor value, then prove it with a low-voltage bench supply.
Keep this to low-voltage learning circuits. Mains, switchboards, fixed wiring, high-current systems, and legal electrical work belong with licensed electricians where required.
