**Unformatted text preview: **3 megawatts, with a characteristic impedance of 500 Ω (two-wire line). What is the peak voltage on the line after the break occurs? Problem P6.2 A very long transmission line with characteristic impedance Z 0 and wave velocity v = c has a shunt resistor of unknown vlue R L at an unknown location z = ± . A measurement of the voltage at the input, V ( t ), with a unit step generator applied to the line, yields the result shown in Fig. 2. ’ V + V + Z o V _ + u(t) Z o , v − V (t) R L ∞ z = 0 ² z = ± z V (t) 10 -8 sec t Fig. 2 (a) What is ± ?
