I need help with working out a physics question.?

Question

A 2200μF capacitor is charged to a potential difference of 6.0V in 3.2s. Calculate the average charging current and the energy stored by the capacitor.

Answer 1

The stored charge Q is VC.
The average current is Q/t.
The stored energy is .5*QV or .5*V^2*C or .5*Q^2/C.
See the ref.
C=0.0022 F, V=6 V, t=3.2 s
