give me some clue how i can manipulate this cu
rrent source back to dc source has anyone known? thanks
The OP is long gone.I'm going to completely embarrass myself and attempt to write loop equations for this....Which WILL BE COMPLETELY WRONG but at least you have something to show you tried.....
I1 = 40V/(4Ohms) + (40V)/(3Ohms) -I2 +6A + (40V/1Ohm)+ (40V-30V/1Ohm) -I4 -I3
I2= -I1 -6A (-30V/1Ohm) -(30V/3Ohm)-(30V/2Ohm)-[(30V-40V)/5Ohms]
I3=-I1 +I2 +6A -(40V/5Ohms)
I4=30V/6Ohm -6A -I3
So, YOU are going to supply loop equations, right or wrong is irrelevant, so that the OP will have something to show that THEY tried?I'm going to completely embarrass myself and attempt to write loop equations for this....Which WILL BE COMPLETELY WRONG but at least you have something to show you tried.....
I1 = 40V/(4Ohms) + (40V)/(3Ohms) -I2 +6A + (40V/1Ohm)+ (40V-30V/1Ohm) -I4 -I3
I2= -I1 -6A (-30V/1Ohm) -(30V/3Ohm)-(30V/2Ohm)-[(30V-40V)/5Ohms]
I3=-I1 +I2 +6A -(40V/5Ohms)
I4=30V/6Ohm -6A -I3
I'm giving you help because you posted an effort to work the problem and I'm willing to help anyone that is willing to try.....I'm astonished by how much you posted I don't even really know why you're giving me help since i don't see you do it in other topics. But here you go, here's my unethical attempt to solve the problem:
node d: (Vd-Vb)/(3Ohms) -6A + (Vd-Vf)/(1 Ohm) = 0
node e: 6A+ (Ve-Vh)/(5Ohms) = 0
node f: (Vf-Ve)/(5 Ohms) +(Vf-Vg)/(1Ohms) + (Vf-Vd)/(1Ohm) = 0
Nope, but we'll get there.node d: (Vd-Vb)/(3Ohms) -6A + Vd-Vh/1Ohm = 0
node e: 6A - 40V +(Ve-Vb)/(2Ohms) = 0
node f: (Vf-Vg)/(1Ohms) + (Vf-Vd)/(1Ohm) - 30V = 0
I think this is it.
I have no idea why it would give you four characters. What kind of keyboard are you using? You need one that has a separate numeric keypad. You can't use the keys above the letters nor can you use the numlock on laptop keyboards that lack a keypad and that turn a section of the letter keys into a numeric keypad (which really sucks). If you are using a smartphone or something like that, I have no idea but it would not surprise me that it doesn't work. So just keep typing out the units, but please do use lower case and do put a space between the numeric part and the units part.Alt 234 does this to me ê ë ìí ï

You can't just say that Vh is 30V. That is only true if you have defined Vf to be 0V, and we haven't defined a reference at all. We could pick any node to be 0V and while Node f isn't unreasonable, arguably a better choice would be Node g.Why do you need both Ve-Vb and Vc-Vb?
node f: (Vf-Vg)/(1Ohms) + (Vf-Vh)/(1Ohm) + (Vh-Vd)/(1Ohm)+(Vf-Ve)/(5Ohms) = 0
or
node f: (Vf-Vg)/(1Ohms) + (Vf-30V)/(1Ohm) + (30V-Vd)/(1Ohm) + (Vf-Ve)/(5Ohms)= 0
What kind of computer and keyboard are you using?When I hold down alt and press 2 3 4 i do the 2 3 4 synchronously and when i do that i get this: ê
This is a dell keyboard, my computer is windows 7 professionalWhat kind of computer and keyboard are you using?
