The attenuation constant of a transmission line, measured in nepers, is defined as the natural logarithm of the ratio of the input current to the line to the output current from the line. If the input current is 240 mA, what is the output current if the line has a 0.35-neper loss?
(1) 55 mA
(2) 84 mA
(3) 169 mA
(4) 265 mA
(5) 325 mA
(6) 341 mA
