capacitance area distance
A parallel plate capacitor with capacitance Co stores charge of the magnitude of Qo on the plate of area Ao separated by distance do. The potential difference across the plate is If the capacitor is attached to a battery and the charge is doubled to 2Qo, what are the ratios
A capacitor C stores charge Q when there is a potential differenceV. When a potential difference of(a)V + 12.5 Volts is used, an extra 45.5 .C of charge is stored.What is the capacitance C?(b)A second capacitor C has a plate separation of 4.5 mm. When theplates are separated an extra 2.0 mmthe capacitance decreases by 7.5 .F. What is the capacitance?
A capacitor stores charge at a potential difference . If the voltage applied by a battery to the capacitor is doubled to :
(a) The capacitance falls to half its initial value and the charge remains the same.
(b) The capacitance and the charge both fall to half their initial values.
(c) The capacitance and the charge both double.
(d) The capacitance remains the same and the charge doubles.
