why there is wrong??

draw circuit in pspice
the circuit from laplace

 

think the problem in source !!

 

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

Did you check the session log?

hello
do the another problem in pspice
please can you check your answer true (question 2) ?

please can you check my answer true (question 2)

 

my draw and solution is true?

 

Did you get the first problem (post #1) solved yet?

hello
now see my answer in (post #4)

 

do by my hand from post #4 true?

 

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))

ok nice , the Vo=0v true?
and I read the question a lot, the question want only t=0 true?
what is mean last step?

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

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

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

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

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

 

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

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

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

please see my solution true?

 

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

They are circled below:

 

do the circuit in Multisim is easy for pspsice

obs! I will change

 

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

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

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

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
