Capacitance (Chapter 26) Capacitance (Chapter 26) Capacitance– theproperty of a conductor or set of conductors and insulators to storeelectric charge Capacitor – an electronic component that has theability to storecharge Definition Calculating Capacitance Dielectrics and Dielectric Constant
Definition : CapacitanceC of two conductors with equal but opposite charges Q C V = V = potential differencecreated when charge+Q is on one conductor, and –Q is on the other. Unit : (F) farad volt coulomb 1 = Typically ranges from 1 μ F = 10 -6 F and 1pF = 10 -12 F 1 F is a LOT of stored charge!!!

1) Find theelectric field as a function of r using Gauss’s Law. 2) Choose a path along a field line: thepotential changewith each small change dr in distanceis dV = - E(r)dr 3) Integratefrom start to end of field lineto find the potential difference.
