Capacitance (Chapter 26) Capacitance (Chapter 26) Capacitance – the property of a conductor or set of conductors and insulators to store electric charge Capacitor – an electronic component that has the ability to store charge Definition Calculating Capacitance Dielectrics and Dielectric Constant

Definition : Capacitance C of two conductors with equal but opposite charges Q C V = V = potential difference created 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 !!!

r using Gauss’s Law. 2) Choose a path along a field line: the potential change with each small change dr in distance is dV = - E(r)dr 3) Integrate from start to end of field line to find the potential difference. 4) C=Q/V
