818.3 Capacitors and Capacitance When the capacitor is charged, the conductors or plates have equal but opposite charges magnitude o For an isolated, ideal, Treminal ig charged capacit e charge separation can last indefinitely 818.3 Capacitors and Capacitance 2. Capacitance The capacitance of a capacitor is defined to be the ratio of the absolute value of the charge on ither conductor to the absolute value of th potential difference between them: (C/Farad(F) The capacitance of a capacitor is a measure of its capacity for holding(storing charge. Note The value of the ratio is independent f either o or v. 1010 When the capacitor is charged, the conductors, or plates have equal but opposite charges of magnitude Q. For an isolated , ideal, charged capacitor, the charge separation can last indefinitely §18.3 Capacitors and Capacitance 2. Capacitance The capacitance of a capacitor is defined to be the ratio of the absolute value of the charge on either conductor to the absolute value of the potential difference between them: V Q C = (C/V)[farad(F)] The capacitance of a capacitor is a measure of its capacity for holding (storing )charge. Note: The value of the ratio is independent of either Q or V. §18.3 Capacitors and Capacitance
