Two conducting spheres of radii R₁ and R₂having charges Q₁ and Q₂respectively are connected to eachother. There is

A series combination of n₁ capacitors each of value C₁, is charged by a source of potential difference 4V. When C₂, is charged by a source of potential difference V, it has the same (total) energy stored in it, as the first combination has, The value of C₂, in terms of C₁, is then

The energy stored in a condenser of capacity C which has been raised to a potential V is given by

Capacitors are used in electrical circuits where appliances need more

If the circumference of a sphere is 2m, then capacitance of sphere in water would be

Eight drops of mercury of equal radii possessing equal charges combine to form a big drop. Then the capacitance of bigger drop compared to each individual small drop is

The potential gradient at which the dielectric of a condenser just gets punctured is called

Separation between the plates of a parallel plate capacitor is d and the area of each plate is A. When a slab of material of dielectric constant k and thickness t(t

The capacity of parallel plate condenser depends on

The energy required to charge a parallel plate condenser of plate separation d and plate area of cross-section A such that the uniform electric fieldbetween the plates is E, is
