$${\mathtt{I1}} = {\mathtt{m}}{\mathtt{\,\times\,}}{\left({\mathtt{R}}{\mathtt{\,\small\textbf+\,}}{\mathtt{R1}}\right)}^{{\mathtt{2}}}$$
$${\mathtt{W1}} = {\frac{{\sqrt{{\frac{{\mathtt{N}}{\mathtt{\,\times\,}}{\mathtt{M}}}{\left({\mathtt{R}}{\mathtt{\,\small\textbf+\,}}{\mathtt{R1}}\right)}}}}}{\left({\mathtt{R}}{\mathtt{\,\small\textbf+\,}}{\mathtt{R1}}\right)}}$$
$${\mathtt{Ek1}} = {\frac{{\mathtt{I1}}{\mathtt{\,\times\,}}{{\mathtt{W1}}}^{{\mathtt{2}}}}{{\mathtt{2}}}}$$ ...?
