.


14.
When a function Z(s) having a pole at infinity is realized, we get
a capacitance in series
a resistance in series
an inductance in series
a resistance or inductance in series
Answer: Option
Explanation:

If we divide numerator by denominator we get term sL.

s Therefore the network has inductance in series.
