For power transmission power loss in line ${P_L} = {i^2}R$
If power of electricity is $P$ and it is transmitted at voltage $V$, then $P = Vi$ $ \Rightarrow $ $m = 6.56\,g/s\,$
${P_L} = {\left( {\frac{P}{V}} \right)^2}R = \frac{{{P^2}R}}{{{V^2}}}$ $ = \frac{{2.2 \times {{10}^3} \times 2.2 \times {{10}^3} \times 10}}{{22000 \times 22000}} = 0.1\,W$
