A small town with a demand of $800\;kw$ of electric power at $220\;v$ is situated $15\;km$ away from an electric plant generating power at $440\;v$. The resistance of the two line wires carrying power is $0.5\;\Omega$ per km. The town gets power from the lines through a $40,000-220\;v$ Step down transformation. Neglect leaked losses . hence explain why high voltage transmission is preferred .

Question

$\begin{array}{1 1} \text{because the power loss percentage at higher voltage is very less } \\ \text{because the power loss percentage at higher voltage is very high } \\ \text{voltage drop on the line is very high } \\ \text{Voltage on the line is very low } \end{array} $
