I suppose their nothing in this circuit that can conflict with finding my solution such as a "trick"

Bump...

Homework Statement I am to find the Thevin and Norton equivalents of the following circuits, my problem being I am new to these method and any help is appreciated also is there any way to simplify this circuit properly?

I got -1A for the current dependent source, does that seem right?

Thanks! I always have a problem with getting the right sign convention here, I've been working on this for multiple hours trying to find a comprehendable explainable solution to my mess. Being that the original direction gets confused with the direction I am trying to take. How do you know...

Thanks for help, so do I label the polarities of the devices based on the direction of each loop I have chosen or based of the direction of the device? I believe super mesh is used for a dependent source or any device shared between a common branch of currents. Also would I put a node on...

Thanks Im in my originating equations I believe when doing super mesh you "pretend" as if the current source in a common branch is there hence the equation for my mesh. Also thanks for the tips on the node method, ill try that out

Well I am not entirely sure if my sign convention for all devices is correct. And which or how many nodes to pick when implementing the node method and what to use when using KCL for node for the middle branch, would I just put the current down that branch as 3Vx, and I just want to see if my...

Dammit! I need this checked by tomorrw morning!

Sigh bump...

Homework Statement Given the following circuit using mesh's method to solve for the power of the dependent source. Using the same circuit and using the node voltage method solve for the power of the dependent source. Circuit: Homework Equations Noting that I have to implement a...

Yeah the fan turns on, and the 5V rail measures 0.01 volts if that, but the fan is wired internally to a positive 12v rail ill test the 12 v rail

Id Imagine that the green wire has to be grounded to get power i ran a voltmeter on it and with the fan just on no output power i got from the 5v rail

I believe the next link on the page is it. The LPX Form Factor http://www.pcguide.com/ref/power/sup/form_BabyAT.htm As for the green terminal it is grounded to the PSU case Thanks for the amazing help I am checking that link out now and will edit this post if need be, once again thanks...

Yes, thanks I've read over several tutorial, through some googling for a few hours, I believe my PSU is maybe an AT, it has an external switch which turns the fan on and off with push push and by the switch is a terminal ring which is green, which I assume in very older motherboards was attached...
