How to construct current controlled current source

I wish to check my solution by using multisim,however, i don't know how to construct a circuit that contain current controlled current source. Hope anyone can help me.Thanks in advance
Solved!
Go to Solution.

Thank for your reply...I have tried to construct the circuit already.But the current that i get from calcuation is 254.8mA, and from the multisim, i get 181.819mA,i dont know which part i connect wrongly.Here is the circuit that i done.

Labeling current controlled voltage source/finding currents

Im studying Thevinen Equivelent circuits,and just got introduced into Multisim.The book briefly tells us how to find currents for components such as resistors by adding a DC Source w/ 0Volts.But when trying to add the dependent current controlled voltage source I dont know what to type in to show its relationship to the current called "Io".Im and ultimatly trying to find the Thev. Equiv. circuit with Voc and Isc.Any help would be great.

Current Controlled Voltage source

Hi everyone,
I've the following circuit, which contents a current controlled voltage source:

I've found it:
http://s27.postimg.org/7l1nllzgv/Untitled.png
But couldn't know how to deal with it.
Any help?

Hi there,
Instead of using the current controlled voltage source, we can place an ABM(Analog Behavior Model) source in Multisim.
After you place the ABM source, double-click it. In the ABM source dialog box, select the value tab. In this value field you can define a mathematical or codniton statement that will act as a stimulus in your circuit.
In this case, let's type: 5*(V(1)-V(0))/2
Here V(1) and V(0) are the net name using the syntax V(<net name>)
Attached is the schematic for reference
Hope it helps!

Current controlled voltage source trouble

Hello, I've searched around and can't find anything that explains why I'm getting errors when trying to simulate this circuit. I would apppreciate any help. I need the votage source on the right to be controlled by the current going through R4, specifically 150 * I(R4). I can't seem to get it to work. Thanks for your time.

MULTISIM need help with placing current dependent current source?

[IMG]http://i56.tinypic.com/ei7a0n.png[/IMG]
as you can see it is a current dependent current source and has value 2*I(x). i have placed it in a circuit in multisim but i have a feeling i'm doing it wrong:
[IMG]http://i54.tinypic.com/2ppezj5.png[/IMG]
and don't worry about the 25-amp resistor at the right it was the load resistor we had to place.

Hello,
Well from the first circuit you have there, you are looking for the current source to output 2x curret passing between the 10ohm resistor and the 19v source. So you need to connect that line to the current controller (the square thing attached to the current source), basically running a wire from the voltage source to one end of the controller, then running the other end of the controller to the 10ohm resistor (deleting the connection between the resistor and the source so that they only connect through the controler).

I want to update iCloud account with new apple id but don't know password for old apple id. Plus can no longer receive email at old apple id. How can I delete the current iCloud account on my iPhone if the previously stated conditions exist?

I want to update iCloud account with new apple id but don't know password for old apple id. Plus can no longer receive email at old apple id. How can I delete the current iCloud account on my iPhone if the previously stated conditions exist?

If the old ID is yours, and if it is an earlier version of your current ID, go to https://appleid.apple.com, click Manage my Apple ID and sign in with your current iCloud ID. Click edit next to the primary email account, change it back to your old email address and save the change. Then edit the name of the account to change it back to your old email address. You can now use your current password to turn off Find My iDevice, even though it prompts you for the password for your old account ID. Then save any photo stream photos that you wish to keep to your camera roll. When finished go to Settings>iCloud, tap Delete Account and choose Delete from My iDevice when prompted (your iCloud data will still be in iCloud). Next, go back to https://appleid.apple.com and change your primary email address and iCloud ID name back to the way it was. Now you can go to Settings>iCloud and sign in with your current iCloud ID and password.

How can I save my current Firefox customization to install on a new Windows 7 installation

This is not asking for a problem fix.
How can I save my current Firefox 3.6 customization, toolbar set-up, plug-ins, add-ons, etc. to a file or files so I can install it, pre-customized, after I do a re-format and clean install of a new Windows 7 operating system?
I am currently in Windows Vista.
I'm just trying to make it so I don't have to re-customize everything I already have done by doing a fresh installation of Firefox.
Or can I just save the existing Mozilla Firefox program folder and then drag and drop it into the new programs folder in Windows 7?
Thanks,
numetro

A couple of links that can help with this, [[Backing up your information]] and [http://kb.mozillazine.org/Profile_backup Profile backup - MozillaZine Knowledge Base]. The second one includes a link to a free utility that can make this easier.
Just saving the progams folder will not work, the user data is stored elsewhere.

Need recommendations for hardware and software - Current control

Hi all,
I am doing a project related to current control.
The purpose is to keep the current at constant. So I measure the current and get the value; and send a analog signal to tell our machine to discharge or to charge in order to keep the current at constant. I need to write the program to give analog signal to machine based on the current input.
Also, the machine can communicate with user. User can monitor the machine operation statuse and current level, etc.
I want to use LabView to program, since it doesn't cost a lot of time. I saw there is LabView RT LabView FPGA, etc. I am confused whether all of these are just diffrent function for LabView or different software. Which one I should use?
For hardware, I have no idea what is compactible with LabVeiw. What I should use?
I am totally new to this. I'll appreciate a lot if anyone can give suggestions.
Thanks

Depending on your budget, operating constraints, timeframe and the transducers you're using a wide variety of equipment might suit your needs. I'd suggest calling the sales department. From NI.com, follow the Contact NI link in the top right corner of the screen. From there you can find information about getting in contact with sales. They help spec out systems all the time.

I hope this answers your question.
If not, post a little sample data (CREATE TABLE and INSERT statements, relevant columns only), and the results you want from that data. If your question is based on commonly available tables, like those in the scott schema, then you don't have to post any sample data: just post the output.
Explain how you get those results from that data.
Always say what version of Oracle (and other relevant softward, SQL*Plus in this case) you're using.

How to save file as "current date-current time"

Hello,
I'm trying to rename a file as from file.mov to "current date-current time"movie.mov, So the final product should be something along the lines of 08-18-08-12:59:08movie.mov (or whatever format the current date/time is in osx). Any ideas on how I would go about this? Thanks again!

Hello Vb,
This script *shows the created date of a file*. Maybe you can do something with it. With a small change it get the date from the finder add adds it to the file.
set selectedFile to (choose file)
tell application "Finder"
set modDate to the modification date of selectedFile
end tell
display dialog "That file was last modified on: " & modDate
This scripts shows *how long ago the file was created*:
--Part 1:
set selectedFile to (choose file)
tell application "Finder"
set modDate to the modification date of selectedFile
--Part 2:
set curDate to the current date
--Part 3:
if (the year of modDate) ≠ (the year of curDate) then
set ageInYears to (the year of curDate) - (the year of modDate)
display dialog "The file was changed " & ageInYears & " years ago."
--Part 4:
else
if (the month of modDate) ≠ (the month of curDate) then
set ageInMonths to (the month of curDate) - (the month of modDate)
display dialog "The file was changed " & ageInMonths & "months ago."
--Part 5
else
if (the day of modDate) ≠ (the day of curDate) then
set ageInDays to (the day of curDate) - (the day of modDate)
display dialog "The file is " & ageInDays & "days old."
else
display dialog "The file was changed today."
end if
end if
end if
end tell

There is a "hidden" setting accessible from the command line ("defaults" command) to change the default screenshot format from png to pdf. Since I always forget the command, I use the free TinkerTool to access/change that setting and others. Screenshot format is found in TinkerTool under "General".

How can I return the current Date in Java?

I am new to Java, and basically I want to know how I can return the current date as a variable, so for example, I have declared the following date variable
private java.util.Date currentDate;How can I return the current date, do I have to write a method? To be more specific, I need to write a setMethod, that simply returns the current Date in Java.
Please point me in the right direction.
Thanks,

If all you want is a date for printing or displaying, the easiest way is to use Date as shown below. If you need something more complex, look at the Calendar API.
import java.util.Date;
class DateEx
     public static void main(String args[])
          Date now = new Date();
          System.out.println(now);
}
