In a schematic diagram, what does the letter "C" represent?

In a schematic diagram, the letter "C" typically represents a capacitor. Capacitors are fundamental electronic components used to store and release electrical energy in circuits. They are marked with the letter "C" followed by a numerical identifier to differentiate between multiple capacitors. This convention is widely used in various schematics to provide clarity regarding the components used in the circuit design.

Understanding this designation is crucial for anyone working on or interpreting schematic diagrams, as it aids in identifying the roles of different components within an electronic circuit, particularly in applications involving filtering, timing, and energy storage. Recognizing that "C" signifies a capacitor helps technicians and engineers quickly locate and address components that will affect the performance of the circuit.
