Then it stops. Call this maximum voltage V. The average voltage across the capacitor whilst it''s being charged is (V/2), so the average power being delivered to it is I (V/2). It was charged for T seconds, so the energy stored in the capacitor is T I (V/2). The charge accumulated on the capacitor is Q = I T, so the total energy stored is Q (V/2).

Capacitance (C) can be calculated as a function of charge an object can store (q) and potential difference (V) between the two plates: C = q V. C = q V. Q depends on the surface area of the conductor plates, while V depends on the distance between the plates and the permittivity of the dielectric between them.
