Question

A spherical capacitor has an internal radius A and an external radius B .Show that it's capacitance is given as C=4πepslon(AB/B-A)

Answer 1

Answer:

The outer sphere si earthed and the inner sphere is given a charge of 2.5 muC. ... (b) What is the potential of the inner sphere ? (c) Compare the capacitance of this capacitor with that of an isolated sphere of radius 12 cm. ... Figure shows three concentric conducting spherical shells with inner and outer shells earthed and ...
