Electronics Academy
Short lessons for the bench and the jobsite.
Each module keeps the language practical: what it is, where it shows up, and what to watch before you wire anything.
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.

AC vs DC
DC flows one way. AC changes direction repeatedly and is used for power distribution.
Resistors
Resistors limit current, divide voltage, set bias points, and turn electrical energy into heat.
Capacitors
Capacitors store charge, smooth supplies, pass changing signals, and block steady DC.
Inductors
Inductors store energy in magnetic fields and resist changes in current.
Transformers
Transformers transfer AC energy through magnetic coupling and change voltage by turns ratio.
Amplifiers
Amplifiers use a small signal to control a larger signal for audio, sensors, and communication.
Speakers
Speakers use a voice coil in a magnetic field to move air and create sound.
Radio Waves
Radio uses electromagnetic waves to carry information through space.
Solar Basics
Solar panels provide variable DC power that needs regulation before charging batteries.
