Description : The coefficient of reflection for current wave is

Last Answer : The coefficient of reflection for current wave is 1 or -1

Description : lf a travelling-wave travelling along a loss-less overhead line does not result in any reflection after it has reached the far end, then the far end of the line is

Last Answer : lf a travelling-wave travelling along a loss-less overhead line does not result in any reflection after it has reached the far end, then the far end of the line is terminated into a resistance equal to surge impedance of the line

Last Answer : When a wave propagates on a transmission line, it suffers reflection several times at sending and other end.
