A capacitor is made out of a sphere and a spherical shell maintained at a constant potential difference as shown in the animation (charges are given in mC and distances are given in centimeters). You may click-drag on the inner sphere to resize it.
What happens to the capacitance of the system when the inner sphere is resized? Note: there is a 1-5% intrinsic error in the calculation of charge. Start
The capacitance increases/decreases as the inner sphere increases/decreases in radius.
