A capacitor has been charged by ad.c. source. What are the magnitudes of conduction and displacement currents, when it is fully charged?

Explanation

When capacitor is fully charged, let q be the
charge on the plate of capacitor, which is
constant.
Electric flux through the plates of capacitor,
`phi_E=q//in_0=a contant `
Displacement current,
`I_D=in_0(dphi_E)/(dt) =in_0(d(q/in_0))/(dt)=0`
Let C be the capacity of capacitor and V be the
pot.diff. between two plates of capacitor when
capacitor is fully charged, then q=CV
Conduction current, `I=(d(CV))/(dt)=C (dV)/(dt)=0`
as V is constant, when capacitor is fully charged.
