OK. Now I see : ). In the solution they actually add the initial voltage afterwards. But then wouldn't my answer be correct? The original question was find Vc(s) for t≥0. This is an actual university exam question. Maybe the capacitor voltage in the laplace domain is defined, or is by convention...
Hey gneill,
When transforming the correct answer back to the time domain Vc(0)= 8 V (the initial potential) as expected. and Vc(infinity)=20 V as expected, contradicting what you said. Did i misunderstand u ?
Homework Statement
