1.   Capacitance in F of a spherical conductor having radius 1 m is

Solution:





2.

A parallel plate capacitor is made by stacking n equally spaced plates connected alternatively. If the capacitance between any two adjacent plats is C, then the resultant capacitance

C

nC

(n-1) C

 (n + 1) C

Solution:
The given system of plates will be equivalent to (n-1) capacitors joined in parallel, each having same capacity C so equivalent capacitance = (n-1)C.

3.

Solution:
