1. We have a two-wire overhead transmission line, powered by a constant voltage source of 700 V. The values for the inductance of the conductors are 2.348x10-3 H/km and the capacitance values are 6.325x10-9 F/km. Assuming an ideal (lossless) line and its length of 130 km, determine the speed at which it propagates.
