    The problem is with L1 and R1, see those green bubbles next to them for more information.

    Did you check the session log?

    Hello,

    In your second to last step in "4.jpg" it looks like you have a "30" when it should be "30000". Doing that fixes it.

    I dont see what you were trying to do for your last step, what is that for?

    The solution should look like A/(s*(s+B))...

    Like this: 37500/(s*(s+2500))

    but I think (2K) * ( 15/s m) = 30/s

    Ix= (R / ( Zl + R )) ( Iin )

    = 2K (15/s )/( 0.8s ) + ( 2K )

    = 30 / s( 0.8s +2K ) A
    true?

    In your first post ... what is the symbol on your pSpice and what is the symbol on your question.

    They are circled below:

    Hi,

    Yeah that doesnt look right because 2000*15 is not 30, it's 30000 (you wrote 2k*15 and got 30 somehow).
    2*15=30
    2k*15=30000
    2k*15=30k not just 30.

    hello MrAl
    (2K) * ( 15/s m) = 30/s
    is mean (2 * 10^3) * ( 15 * 10^-3/s ) = 30/s ;)
    thanks
