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?
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...

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.

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...
I managed to pick up a few years old PSU from the computer science professor at college :D, If anyone remembers my post a few weeks ago I was very enthusiastic about this. However, I've identified all wires labeled and from the standard tutorials on the internet, the white wire typically listed...
Wow, this is very similar to my course. Here are some idea's by past students at my university. Enjoy.
1. Measure the speed of sound over a calibrated distance and display its value and the time required to travel the calibrated distance.
2. Develope a motor speed control with optical...
Ah, yes berkman that would be very challenging.
I also like the last idea allowing the PIC weather station to connect to a wired or wireless network where It can upload the new data every so often, say every 5 minutes. Only that sucks I am probalby the most knowledge programmer in the group...
Please, do not tell me to go google this, and searching these forums. I am perfectly capable of doing so. However, I am posting here to hear unique idea's something google cannot find, to me at least, as any good hobbyist/engineer are always having random sparks of creativity anywhere, any time...
Thanks! The exact derivation I was looking for. Also, thanks for the tips, I tried deriving the equation myself ,and, looking up google for some quick references, but that was a no go just gave the equations themselves.I was unsure of what to substitute, however, is this equation only limited...
Thanks for the input, I am just a very trivial person, I like to know how things are derived, kind of biting me in the read in my subjects of interest, maths, etc. something are the way they are. I just want to know when/how to derive these things with proper analytically explanation.
I am wondering how is the third equatio of motion derived, I was reading a text on my physics course which it is very unclear how they exactly they arrived to this equation, knowing this from the book, using the equations for velocity and position, you can combine them to get 3 new equations of...

I had posted another thread a week ago where I was given a function q(t) that t was defined in millisecond, and I had to evaluate q(t) at 0 and infinity then I had to do the same thing when I found the current I(t) in Coulombs/ms, Now i have do the same further more by...

I've seen this problem on here only twice, once never answered, and the other just saying the OP's "solution" was on the right track

Ok, lets see here for the first constant speed of 30 km/h, I am gonna pick an arbritary distance of 25 km for both speed constants
Speed:30 km/h
Distance: 25
Time: 0.83
Next speed constant
Speed: 66 km/h
Distance: 25
Time:0.3787
Average Speed
\frac{25}{1.2087}=20.68 km/h
Picking...
Hmm as if the car is going the same amount of time at both speeds....
This question is just a tad confusing, pick an arbitrary distance to find the how long each trip takes
something like this? Say I pick 25 km for the distance
30\frac{km}{h} = \frac{25 km}{t}
