Question

A capacitor consists of two closely spaced metal conductors of large area, separated by a thin insulating foil. It has an electrical capacity of 4000.0 μF and is charged to a potential difference of 69.0 V. Calculate the amount of energy stored in the capacitor, 9.52 J You are correct. Previous Tries Calculate the charge on this capacitor when the electrical energy stored in the capacitor is 12.17 J. .2759 C The capacitance is the same as in the previous problem, but not the potential difference. There is an equal amount of charge on each plate, with + and - sign. The charge on the capacitor refers to the magnitude of the charge on one of the plate. Submit Answer Incorrect. Tries 5/20 Previous Tries If the two plates of the capacitor have their separation increased by a factor of 3 while the charge on the plates remains constant, bý what factor is the energy stored in the capacitor increased? Remember the relation between distance and capacitance, then see how the stored energy changes when you change the capacitance (constant Q
