Statement of a problem № 41201


The radii of spherical capacitor electrodes are equal to a and b, with a < b. The interelectrode space is filled with homogeneous substance of permittivity e and resistivity p. Initially the capacitor is not charged. At the moment t = 0 the internal electrode gets a charge q0. Find: (a) The time variation of the charge on the internal electrode; (b) The amount of heat generated during the spreading of the charge.
