The capacitors, each of $$4 \mu \mathrm{F}$$ are to be connected in such a way that the effective capacitance of the combination is $$6 \mu \mathrm{F}...

A variable capacitor is connected to a 200 V battery. If its capacitance is changed from 2 $$\mu$$F to X $$\mu$$F, the decrease in energy of the capac...

A capacitor is a system of two conductors separated by an insulator. The two conductors have equal and opposite charges with a potential difference be...

(a) Two charged conducting spheres of radii $$a$$ and $$b$$ are connected to each other by a wire. Find the ratio of the electric fields at their surf...
