The link below shows a circuit and the s-domain equation for I1(s) that I have derived; My question is on the portion of the equation containing the "(s+a)" terms. I am trying to arrive at the time-domain equation for I1(s) but instead of arriving at the Laplace transform pair shown in the link below my math ends up with an extra "a" term in the numerator as shown. I cannot find a Laplace transform pair for the s-domain equation that I end up (as shown in the link below). Have I made an error in the derivation? Has anyone derived this solution? Thanks.(adsbygoogle = window.adsbygoogle || []).push({});
