Symbols - Capacitor

	Non Polarized Capacitor Capacitor stores the charge in the form of electrical energy. These two symbols are used for non-polarized capacitor. Non-polarized capacitors are big in size with small capacitance. They can be used in both AC and DC circuits.
	Polarized Capacitor Polarized capacitors are small in size but have high capacitance. They are used in DC circuits. They can be used as filters, for bypassing or passing low frequency signals
	Electrolytic Capacitor Almost all electrolytic capacitors are polarized and hence used in DC circuits
	Feed through Capacitor They provide low impedance path to ground for high frequency signals
	Variable Capacitor The capacitance of the variable capacitor can be adjusted by turning the knob. They are widely used to adjust the frequency , that is for tuning.
