ideal op amp

Above is a circuit which has given me, and the only instructions given is the following:

Multisim allows to solve following problems. Use of multimeters for results required for given circuit.

  1. IL find (in microamperes)  in the circuit in the figure below.

Can anyone help? I am at a total loss and have been tought NOTHING about the use of multisim... below is the circuit that I built.

I can't help but feel that it's wrong, I took a random op amp in the giant list of them... the instructions do not specify which one to use.  But I say, everything that we've done on paper we must assume that this is an ideal op amp.  Please help if you can, I'm pretty confused at this point...

The AD827 probably isn't a particularly good choice for such a circuit, it is a video driver for applications with MHz bandwidths, but it should work.

This is the correct connection for the ammeter.

It is hard to tell from the image, but it seems that you have swapped power supplies.  According to the data sheet Analog Devices the Q package has V + on pin 8 and V - on pin 4.

  • How can I mix and match different amps and cabinets?

    I'm running Logic Pro and still have a problem with the amp Designer. I read in the world how it is easy to mix and match different amps, cabs and pickups but the drop down menus where I should be able to select them all are disabled. I can browse all presets of course, but I can't mix and match.

    I found some advanced tools in the preferences and activated all the boxes in there, just to see. The question remains the same.

    No idea how I could get these options enabled?

    No problem here. Once you select a different amp and Cabinet, you should see 'tailor-made' next to the model on the left.

    I don't think that the patches have nothing to do with him, but have you downloaded all the additional sounds, in particular "the guitar"?

    Hope that helps

  • How many watts/amps are SD-R2412 and other slimline toshiba drives?

    How many watts/amps is this reader of CD/DVD-SD-R2412 and other toshiba slimline drives?

    I'm not sure which forum to post this question in.

    I found this link on the site of toshiba American (or maybe Googling with site: toshiba.com)
    http://SDD.Toshiba.com/main.aspx?path=HardDrivesOpticalDrives/CDCombination/SD-R2412/SD-R2412Specifications

    But it doesn't say how many amps on the 5V line. If I had known that I would like to know how many watts. I am interested by this.

    And also for others.

    Just a question; Why you want to know?

    I mean us normal users won't get these details as you need. A possibility might be possible:

    Look on the label that is on the drive, maybe you can get the information from there you'd like to know...

    We got a new Denon amp today, her husband wanted to whoever he could plug the laptop and listen to the large amount of music that has accumulated on the subject.
    Now the Denon's HDMI inputs and it supports also HD audio (unlike the Kenwood, they we sold yesterday said they made and after a very frustrating night of do not get it to work, short, it didn't!)

    Now we can connect the computer via HDMI to plasma Hitachi and get a very good picture and sound, plug it into the amp and we get picture but no sound, tried to do what the FAQ says to do and right click on the wallpaper, then customize, then sounds and set HDMI as dafult. Problem is when taking HDMI is connected, the HDMI option to set default disappears! As soon as you unplug the HDMI, it appears again.

    What the devil we do wrong?

    Thanks for any help you can give us :)

    Generally, the USB ports provide 500mA.
    USB voltage values are know not to me but to my knowledge all the USB ports must supports USB standards.
