Chapter 5 Capacitance and Dielectrics
capacitance is a measure of the capacity of storing electric charge for a given potential difference ∆V. The SI unit of capacitance is the farad (F): 1 F ==1 farad 1 coulomb volt= 1 C V A typical capacitance is in the picofarad ( ) to millifarad range, ( ). 1 pF=10−12F 1 mF==10−−36F=1000µµF; 1 F 10 F
AC Capacitance and Capacitive Reactance
Capacitors store energy on their conductive plates in the form of an electrical charge. The amount of charge, (Q) stored in a capacitor is linearly proportional to the voltage across the plates. Thus AC capacitance is a measure of the capacity a capacitor has for storing electric charge when connected to a sinusoidal AC supply.

How do capacitors work?
How do we measure capacitance? The size of a capacitor is measured in units called farads (F), named for English electrical pioneer Michael Faraday (1791–1867). One farad is a huge amount of capacitance so, in practice, most of the capacitors we come across are just fractions of a farad—typically microfarads (millionths of a farad, written ...
