Let R be the resistance of each conductor in a DC 2-wire with a midpoint earthed transmission system. What is the copper loss in the system to transmit the power P?
1
\(\frac{{{P^2}}}{{2{V^2}}}R \)
2
\(2{\left( {\frac{P}{V}} \right)^2}R \)
3
\(\frac{{{P^2}}}{{{V^2}}}R\)
4
\(4{\left( {\frac{P}{V}} \right)^2}R\)
