Electromagnetic Field Theory

Q1:

The input impedance of short-circuited line of length l where λ/4 < l < λ/2, is

A resistive

B inductive

C capacitive

D none of the above

ANS:C - capacitive

l < λ/4, ZL = 0 , if Zd comes +j kZC then inductive, If Zd comes -j kZC then capacitive. for 0 ≤ l ≤ 1/4, λ ≤ l ≤ 3λ/4 will be inductive.
