![]() ![]() The location of voltage minimum is on the left because. A Smith chart is developed by examining the load where the impedance must be matched. The location of voltage minimum is on Question: QUESTION 23 Which of the followings is true On Smith chart O A. (f) The position of the first voltage maximum from the load. The location of voltage minimum is on the left because the admittance is minimum. Use the Smith chart to find the following: (a) The reflection coefficient. Find the normalized load admittance at a distance of 0.4 from the load, using the Smith. 6) A 50 transmission line (i.e., the characteristic impedance is 50 has a load impedance of Z L 30 + j (75). Use the smith chart to find a) voltage reflection coefficient, b) the voltage standing-wave ratio, c) the distances of the first voltage maximum and first voltage minimum from the load, d) the input impedance of the line, given the line is 3.3, and e) the input admittance of the line. Similarly, voltage minimum (destructive interference) value corresponds to V. The location of voltage minimum is on the left because the impedance is minimum. At z -0.10 the real part of the impedance is 60. With this device the SWR and the distance of the first voltage minimum from the load.
