The difference between the radill of the two spheres of a spherical capacitor is increased. Will the capacitance increase or decrease ?

Text Solution

Verified by Experts

Thecapacitance C decreases as `C = (4pi in_(0) ab)/(b-a)` , where a,b are radil of two spheres. So if `b-a` increases , capacitance C will decreases.
