Electronics — CompTIA A+ Core 1 (220-1101) Practice Questions

Electronics knowledge relevant to the 220-1101 exam centers on understanding basic concepts such as voltage, current, resistance, and how components like resistors, capacitors, and transistors function within a circuit. Technicians need this foundation to safely handle computer hardware, interpret multimeter readings, and understand why electrostatic discharge (ESD) can permanently damage sensitive components. The exam does not require deep electrical engineering knowledge, but a working understanding of these principles supports proper tool use and safe repair practices.
