CAPACITANCE AND CAPACITOR

CAPACITANCE

The ratio between electric charge and voltage Q/V is called capacitance. The unit of capacitance is ‘Farad’. Electric charge (Q) unit is coulomb.

The farad (F) is a very large unit and in practice capacitance are usually measured in uF (Micro Farad) or (Pico Farad) pF.

1 Farad                 =             1/1000 000          =             10 uF

Capacitor:
The component possessing the property of capacitance is called capacitor.

there are tow types of capacitor;

(1)Fixed Capacitor


(2) Variable capacitor
