To derive the expression for the capacitance of a spherical capacitor, we can follow these steps: ### Step 1: Define the Spherical Capacitor A spherical capacitor consists of two concentric spherical conductors. Let the inner sphere have a radius \( B \) and the outer sphere have a radius \( A \). ### Step 2: Understand Charge Distribution When a charge \( Q \) is placed on the inner sphere, it induces a charge of \( -Q \) on the inner surface of the outer sphere. The outer sphere will have a net charge of \( 0 \) since it is neutral overall. ...
