PHY2061 R. D. Field Department of Physics chp30_1.doc University of Florida Capacitors & Capacitance Capacitor: Any arrangement of conductors that is used to store electric charge ( will also store electric potential energy ). Capacitance: C=Q/V or C=Q/ V Units: 1 farad = 1 F = 1 C/1 V 1 µ F=10 -6 F 1 nF=10 -9 F 1 pF=10 -12 F Stored Energy: U Q V Q C C V co n d u cto r = = = 1 2 2 1 2 2 2 where Q is the charge on the conductor and V is the electric potential of the conductor and C is the capacitance of the conductor.
