Semiconductor physics and bench circuit assembly comprise Grade 10 Electrical Technology in Term 3, scheduling 33 technical periods across 10 pages, introducing learners to diode rectification and transistor switching through breadboard setups and multi-tester measurements.
- Semiconductor Theory: explaining atomic valence bands, crystal doping processes, and charge carrier behaviour in extrinsic silicon during week 1.
- Diode Characteristics: wiring PN junctions in forward and reverse bias, observing knee voltages, and assembling half-wave rectifier circuits across weeks 2 and 3.
- Bipolar Junction Transistors: connecting NPN transistors in common-emitter mode to drive light-dependent resistors and miniature relays in weeks 4 and 5.
- Circuit Prototyping: simulating electronic designs on computer software, assembling prototype boards, and managing electronic scrap during weeks 6 to 9.
Laboratory evaluations involve mid-term checks in week 7 and circuit testing assessments during week 9.
