The solution of differential equations for networks is of the form?(a) i(t)=Kn e^⁡(sn t)(b) i(t)=Kn e⁡^(-sn t)(c) i(t)=-Kn e⁡^(-sn t)(d) i(t)=-Kn e⁡^(sn t)I have been asked this question by my college director while I was bunking the class.This intriguing question originated from The Concept of Complex Frequency in chapter S-Domain Analysis of Network Theory

Answer»

Right option is (a) i(t)=Kn e^⁡(sn t)

Explanation: The SOLUTION of differential equations for networks is of the form

i(t)=Kne^⁡(sn t) where Sn is a complex NUMBER which is a ROOT of the CHARACTERISTIC EQUATION.
