What standing wave ratio results from connecting a 50-ohm feed line to a 10-ohm resistive load?
2:1
1:2
1:5
5:1✓الإجابة الصحيحة
الشرح
Here the line impedance is the larger value, so the ratio is 50/10 = 5, giving 5:1. The mismatch produces the same SWR whether the load is five times too high or five times too low.
