Consider a 300 Ω, quarter wave long at 1 GHz transmission line as shown in figure. It is connected to a 10 V, 50 Ω source at one end is left open circuited at the other end. The magnitude of the voltage at the open circuit end of the line is

195-222-1
[A]. 10 V
[B]. 5 V
[C]. 60 V
[D]. 60/7 volt

Answer: Option A

Explanation:

γ = a + jβ a = 01-sym-impγ = jβ

Propagating wave

v = VI e-rz + VR erz

No change in the voltage at the open end it will same,

vr = 10 volt.
