Basics#
The first layer of the bench discipline. Electricity, parts, the symbols that draw them, and the simple circuits they form before semiconductors become a chip.
Electricity
Static, current, voltage, resistance, AC and DC, and the shapes signals take on the wire.
Components
Wire, switches, relays, meters, resistors, capacitors, coils, transformers, and the historical hacking-device catalog.
Semiconductors
Diodes, transistors (bipolar and FET), the UJT, and the thyristor family.
Photonics
LEDs, laser diodes, photodiodes, phototransistors, photothyristors, solar cells, and the photoresistive predecessors.
Symbols
Schematic symbols and example circuits drawn in standard IEC / IEEE notation.
