I'm perfectly aware of what unit it should come out as and why. ☺

I just don't get why Maple can't make the calculation correctly. 😕

@Carl Love 

I know. But I like using units. 

It's a ingeneering class different currents in systems. 

I can see that the problem isn't quiet clear..

In the result Maple is giving me some Z values and RootOF which I don't get... And I can't get a better answer with the simplify option..
