Thank you

 

Look , my circuit is very simple just 1k resister, ac power supplyand ground why i got 0 for the whole interval ?

 

Even if i add new roisters the power still 0 all the time why ?

 

You aren't giving us a whole lot to work with. Post your schematics. Post your output waveforms. Otherwise you are asking us to use crystal balls to divine what you have actually been doing.

 

I am so sorry but i tried many time to upload the picture but it didn't if you do not mind could you give me your e mail to send it to you and upload it for me ?

 

Here it is

Absolutely not. I guard my e-mail addresses very zealously.

You said you took a screen shot of your schematic and that it is in a JPG file format. How big is the file? If it is more than a few hundred kilobytes, please scale it to something reasonable. If you open it in Paint you can resize it to something like 400 to 600 pixels wide. If it is a screen capture, then save it as a PNG file and you will usually get much better compression. If it is a photo take with a cell phone (or similar), then JPEG is probably the best option.

Then click the Upload a File button just below the dialog you are typing your response into.

Try that and if it doesn't work report back with the EXACT steps you are trying to use.

 

You have no transient source values.
The AC source voltage is only for AC small signal analysis, not transient.
Right click on V1 and select the appropriate source on the left side of the pop-up window (Sine if you want an AC signal) along with the other pertinent signal values (amplitude, frequency, etc.).

Plot your voltage and your current waveforms as well.

If those look fine, then the problem is possibly that you are not specifying your expression properly. Some simulators might require you to surround the expression in curly braces.

 

And how i can do the on spice it is actually my first time to use it

There are lots of online tutorials to learn almost any simulation package -- the package probably has some that come with it. You need to work through a bunch of tutorials to learn the software you are trying to use.

 

I didn't found any helpful toturails and that is why i am asking here

See my previous post.

 

this is my asc file

 

is this ok?

 

is this ok?

No. As I previously stated, that AC value on the right is for an AC small signal analysis (as it plainly states).
You need to select a function from the left of that window (pulse, sine, etc.) to do a Transient analysis.
That's as simple as I can make it.

 

Here's an example of what Crutschow is describing:

BTW, try using the F1 key to summon the LTspice Help!

 

Ok thank you but what is the function ?

 

You choose the function. In the example I showed it is Sine. See, top left corner of the pic?

 

What is wrong why i get error in csw?
