PHY2061 R. D. Field Department of Physics chp30_1.doc University of Florida Capacitors & Capacitance Capacitor: Any arrangement of conductorsthat is used to store electric charge (will also store electric potential energy). Capacitance: C=Q/V or C=Q/∆VUnits: 1 farad = 1 F = 1 C/1 V 1 µF=10-6F 1 nF=10-9F 1 pF=10-12F Stored Energy: UQVQCCVconductor===1221222where Qis the charge on the conductor and Vis the electric potential of the conductor and Cis the capacitance of the conductor.
