What symbol is commonly used for capacitors in circuit diagrams?

The symbol typically used for capacitors in circuit diagrams consists of two parallel lines, which represent the plates of the capacitor. This design effectively communicates the fundamental concept of a capacitor, which is to store an electric charge between these two conductive plates, separated by an insulating material or dielectric.

The use of parallel lines in the symbol makes it easy for individuals reading the schematic to quickly identify where capacitance is present in the circuit. This visual representation aligns with the physical characteristics of capacitors, enabling a clearer understanding of their role in electrical designs. Understanding this symbol is essential for anyone working with or studying electrical circuits, as it aids in interpreting diagrams accurately and comprehending how capacitors function within those circuits.
