Capacitors
Capacitors Capacitors are also called as condensers generally used to store electric charge. The unit of capacitance is Farad(F) 1 F = 10,00000 microfarad 1 microfarad = 1000 nanofarad (nf) 1 nf = 1000 Picofarad (pf) Types of capacitors Capacitors can be divided in to fixed capacitors and variables capacitors, Fixed capacitors Fixed capacitors are classified in to two categories the polarised capacitors and non polarised capacitors. Electrolytic capacitors are generally polarised capacitors. They have negative and positive poles. Examples of fixed capacitors 1 ceramic capacitors 2 paper capacitors 3 polyester capacitors 4 mica capacitors 5 electrolytic capacitors. Ceramic capacitors These capacitors are small in size, and very cheap. Which are widely used in Electronic circuits. In this capacitor ceramic materials used as dielectric. Dielectric meas the material used in between two plates of a capacitor to separate them. SMD ( surface mound di
