It is a passive electronic device, used to store a charge. Detail Classification of Capacitor is listed Below: A) Fixed value Capacitor a)Electrolytic capacitor(Polar)(e.g. Aluminum electrolytic capacitor, Tantalum electrolytic capacitor) b) Non-Electrolytic capacitor(Non-Ploar)(e.g. Mica capacitor, Paper capacitor, Ceramic capacitor, Air capacitor) B)Variable value capacitor a)Air Gang Capacitors b) Trimmers and padders Aluminum electrolytic capacitor : Construction: enter image description here Aluminum electrolytic capacitor are constructed by placing dielectric between two conducting material. To form conducting material Aluminum foil is used. A layer of aluminium oxide is deposited to form thin dielectric material

Advantage: Very High capacitance Small in size

Disadvantage: Polarized Limited life span High loss Capacitance change with time and temperature Capacitance range 5 uF to 2000 uF( approx..)

Applications: When high capacitance are required DC applications Smoothening of voltage Coupling
