The [email protected]@ associated with the charging of the @[email protected] at an electrode-solution @[email protected], given by: \[i_{\mathrm{DL}}=\frac{\mathrm{d}(\sigma \ A)}{\mathrm{d}t}\] where \(\sigma \) = @[email protected] of the double layer, \(A\) = area of the electrode-solution @[email protected] and \(t\) = time. Capital letters should be used as subscripts to avoid the possibility of confusing this symbol with that for the @[email protected]
