A parallel-plate capacitor having plate area $A$ and plate separation $d$ is joined to a battery of emf $E$ and internal resistance $R$ at $t=0$. Consider a plane surface of area $A/2$, parallel to the plates and situated symmetrically between them. If the displacement current through this surface as a function of time is given as:

$i_d=\frac{E}{nR}{e}^{-\frac{td}{{\epsilon }_{0}AR}}$

Where, ${\epsilon }_0$ is the permittivity of free space.



The value of $n$ is :
