What happens if the magnitude of capacitance of capacitor are large ? Define dielectric breakdown and dielectric strength.

The capacitance of a parallel plate condenser does not depend on

The potentials of the two plates of capacitor are $+10\,V$ and $-10\, V$. The charge on one of the plates is $40 \,C$. The capacitance of the capacitor is……..$F$

A cylindrical capacitor has two co-axial cylinders of length $20 \,cm$ and radii $2 r$ and $r$. Inner cylinder is given a charge $10 \,\mu C$ and outer cylinder a charge of $-10 \,\mu C$. The potential difference between the two cylinders will be

The potential to which a conductor is raised, depends on
