Laplace Analysis of Step Response of a Parallel RC Circuit

simulate this circuit – Schematic created using CircuitLab

My KCL Equation: $$\frac{Cdv}{dt} + iΔ(t) = \frac{Vo}{10k} + iΔ$$

My laplace transform is: $$\frac{Vo(s)}{s} = \frac{sVc(s)}{20} - 0.00005$$

The circuit and my initial solution is shown in the picture. I'm not sure if even my KVL equation is right. But the way I understood the circuit, because m=1, then the dependent source will have the same current magnitude as the current on its right, hence, because of the opposite direction, they will just cancel out.

The part i'm having trouble with is the laplace transform (which I have to convert back to time domain after). Did I do it right? If yes, for my resulting laplace transform of the equation, how would I find Vc(s)? Is not that Vc(s) and Vo(s) is just the same voltage? How would that work out with the equation?

Then the last question was asking for m that will make Vo(t) boundless and i'm unsure where to start.

• Don’t put units inside equations - this is not good practice, and leads to errors. Think about turning the current source into a voltage source. – Chu Oct 7 '20 at 6:55
• @Chu I was hesitant to put the units too. Ill remember that advice! Also, do you mean the dependent source? – user263783 Oct 7 '20 at 7:12
