A single-phase line consists of two long solid conductors, each having a radius of r metre separated by a distance of D metre. What will be capacitance between the

\(\frac{{0.121}}{{\log \left( {\frac{r}{D}} \right)}}\mu F/km\)

\(\frac{{0.121}}{{\log \left( {\frac{D}{r}} \right)}}\mu F/km\)

\(\frac{{0.0121}}{{\log \left( {\frac{D}{r}} \right)}}\mu F/km\)

\(0.0121 \times \log \left( {\frac{D}{r}} \right)\mu F/km\)
