Basic Electrical Components
Basic electrical components — resistors, capacitors, inductors, diodes, transistors, fuses, relays — are the building blocks of every control board, sensor circuit, and instrumentation panel on a battery production line. As a hard skill it requires reading component markings and tolerances, calculating expected voltages and currents, and recognizing failure modes (burnt resistors, swollen caps) during troubleshooting. Technicians apply this knowledge daily on the line: identifying a blown fuse on a coater drive, spotting a leaking electrolytic cap on a BMS PCB, or sizing a pull-up resistor on a sensor signal line.
