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

Circuit components are the individual electronic parts, such as resistors, capacitors, diodes, transistors, and integrated circuits, that make up the functional assemblies on a motherboard or expansion card. On the 220-1101 exam, recognizing common components by appearance and understanding their general roles helps technicians identify physical damage, understand failure modes, and make informed decisions about whether a component-level repair or full board replacement is warranted. Practical knowledge includes identifying swollen capacitors, burned components, and damaged traces.
