5.15: Changing the Distance Between the Plates of a Capacitor
No headers If you gradually increase the distance between the plates of a capacitor (although always keeping it sufficiently small so that the field is uniform) does the intensity of the field change or does it stay the same? If the former, does it increase or decrease?
It is interesting to note that you can get capacitance of a single spherical conductor from this formula by taking the radius of the outer shell to infinity, (R_2rightarrow inftytext{.}) Since we will have only one sphere, let us denote its radius by (Rtext{.})
