Question T6C06
From subelement T6 - T6C
What is component 6 in figure T-2?
Why is this correct?
Component 6 in figure T-2 is a capacitor, shown by the standard schematic symbol of two parallel lines representing conductive plates separated by a gap (the dielectric). This symbol distinguishes capacitors from resistors (zigzag or rectangle), transistors (circles with leads), and integrated circuits (rectangles with multiple pins). The parallel-plate symbol directly represents a capacitor's physical structure.
Memory tip
Remember the visual logic: capacitor symbols mirror their physical construction. The two parallel lines in the symbol represent the two conductive plates, while the gap between them represents the insulating dielectric material. This direct symbol-to-structure relationship makes capacitor identification straightforward in any schematic.

Capacitors store energy in electric fields between their conductive plates, making them essential for filtering power supplies, coupling AC signals between circuit stages, and tuning resonant circuits in amateur radio equipment. Their ability to block DC while passing AC makes them invaluable for separating different voltage levels in transceivers and amplifiers while maintaining signal paths.
Think about it
Why do you think capacitor symbols use parallel lines rather than some other geometric shape to represent this component?
