RRB Paper · Accepted Answer

The capacitance of the single-phase transmission line can be calculated using the formula:

C = (πε?) / ln(D/d)

Where,
ε? = permittivity of free space = 8.854 x 10^-12 F/m
D = distance between the centers of the conductors = 4 m
d = diameter of each conductor = 2 cm = 0.02 m

C = (πε?) / ln(D/d) = (π × 8.854 x 10^-12) / ln(400/2) = 5.247 x 10^-3 F/km

Therefore, the capacitance of the line per km is 5.247 x 10^-3 F/km

A single-phase transmission line has 2 parallel conductors 4m apart radius of each conductor being 2 cm. Calculate the capacitance of the line per Km given that Eo = 8.854 x 10^-12 F/m

6.12 x 10-3 F/m

6.48 x 10-3 F/m

5.247 x 10-3 F/m

7.248 x 10-3 F/m

The correct answer is `No. 3: 5.247 x 10-3 F/m`
