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

resistive
inductive
capacitive
none of the above

Correct Answer: capacitive

Explanation:

l < λ/4, Z_L = 0

, if Z_d comes +j kZ_C then inductive,

If Z_d comes -j kZ_C then capacitive.

for 0 ≤ l ≤ 1/4, λ ≤ l ≤ 3λ/4 will be inductive.
