how to cal calculate capacitance in DC Circuit

how to cal calculate capacitance in DC Circuit ..

Capacitance in DC circuit is calculated as follows.

1)From dimensinal and medium data

C=(A*e)/d
where A=cross sectional area of conductor.
e=permittivity of medium between conductors.
d=physical distance between conductors.

2)From electrical data.

C=Q/V
where Q=charge on conductor
V=potential differece between conductors.
