Capacitance and its physical significance

Generally, capacity tells about the ability of strength of particular one. When we come to electrostatics in which the capacitance has the meaning but here is what is the quantity denotes about the capacity is that the charge ability of particular device.
Like different containers have difference capacities to fill the liquid, different conductors have the difference capacities to hold the charge. The capacity of a conductor to hold the charge is called
capacitance which is analogous to the volume of container to fill the liquid. Capacitance of a conductor depends on the size, shape and surroundings of the conductor.
In case of isolated conductor, when the charge on the conductor is gradually increases, then its potential will also be increased gradually. Therefore, the charge on the conductor is proportional to the potential.
