Understanding Capacitor Symbols
Understanding capacitor symbols is important as a designer as it helps you to interpret your circuit design. Moreover, different types of capacitors have unique characteristics which you must know to correctly troubleshoot the design. From basic to non-polarized capacitor symbols, you must select the appropriate component for specific applications.
