  • Question

  • Consider a 300 ?, quarter wave long at 1 GHz transmission line as shown in figure. It is connected to a 10 V, 50 ? 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
    Consider a 300 ?, quarter wave long at 1 GHz transmission line as shown in figure. It is connected t


  • Options
  • A. 10 V
  • B. 5 V
  • C. 60 V
  • D. 60/7 volt

  • Correct Answer
  • 10 V 

    Explanation
    ? = a + j? a = 0 ⟹ ? = j?

    Propagating wave

    v = VI e-rz + VR erz

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

    vr = 10 volt.
