State and explain Nernst equation with help of a metallic electrode and non metallic electrode

Nernst Equation: The equation which helps to find electrode potential of an electrode at given
concentration is known as Nernst equation
For Metal electrode: $\left({\mathrm{M}}_{\left(\mathrm{aq}\right)}^{+\mathrm{n}}+{\mathrm{ne}}^{-}\to \underset{\left(\mathrm{s}\right)}{\mathrm{M}}\right)$
$\begin{array}{l}{\mathrm{E}}_{{\mathrm{M}}^{+\mathrm{n}}/\mathrm{M}}={\mathrm{E}}_{{\mathrm{M}}^{+\mathrm{n}}/\mathrm{m}}^0+\frac{0.059}{\mathrm{n}}\log \left[{\mathrm{m}}^{+\mathrm{n}}\right]\\ ={\mathrm{E}}^0\frac{+0.059}{\mathrm{n}}\log \left(\mathrm{c}\right)\end{array}$
For non-metal electrodes $\left(\mathrm{A}+{\mathrm{ne}}^{-}\to {\mathrm{A}}^{\mathrm{n}-}\right)$
$\begin{array}{l}{\mathrm{E}}_{\mathrm{A}/{\mathrm{A}}^{-\mathrm{n}}}={\mathrm{E}}_{\mathrm{A}/{\mathrm{A}}^{-\mathrm{n}}}^0-\frac{0.059}{\mathrm{n}}\log \left[{\mathrm{A}}^{-\mathrm{n}}\right]\\ ={\mathrm{E}}^0 -\frac{0.059}{\mathrm{n}}\log \left(\mathrm{c}\right)\end{array}$
