Consider a capacitor with two circular plates with radii connected to a battery and being charged.
\n\n
Let and be the conduction and displacement current respectively and area of the plates be
\n\n
So, the conduction current can be given as
\n\n\n\n
And displacement current can be given as
\n\n
Here is the permittivity of free space and is the electric flux.
\n\n
Now, there will be an electric field development due to the charge accumulation on the plates which is given as
\n\n
and is the charge density that gives
\n\n
As we know electric flux is given by
\n\n\n\n
Now, using 1 and 3 we get;
\n\n\n\n
Hence, from we get that and in the same direction as both have same sign.
