Homework Statement A counter has two state outputs y1 (the more significant bit) and y2 (the less significant bit) and a control input x. When x = 0, the states of the counter’s flip-flops do not change. When x = 1, the states of the counter’s flip-flops cycle through the codes of a 2-bit Gray...

Sorry, I meant to say that the voltage across the resistor will be 0.

How come I can just assume that the 30k ohm resistor will be 0 when I short a and b. My professor made did this same thing in class with another problem and a lot of things I've been reading do the same. I'll redo the problem with the -0.008 A as well.

So I should just try solving the circuit as given originally?

By turn pot, do you mean trim pot?

Isn't that what the superposition method is though? Closing independent sources and solving circuits with only one source at a time. So don't I need two separate circuits with only a current source or a voltage source?

I'm having a hard time understanding this, is my circuit drawing correct? Because isn't the 60 not just i1?, isn't it 60(i1-i0)?

Homework Statement Find v0 and i0 http://img214.imageshack.us/img214/2051/superquestion.jpg Homework Equations KVL and KCLThe Attempt at a Solution I removed the voltage source and redrew the circuit with a short on the bottom left. I then used mesh current analysis with KVL and made a system...

Ok, then the entire equation for voltage at node A is: (VA-30)/15 + (VA-VB)/25 + (VA-VD)/31.25 - 4 = 0? After I solve for all the voltages at the nodes, how do I find power at the independent voltage a current sources? Do I just use voltage drops? IE, Power at 4A = (VA-VB)*4

Homework Statement Homework Equations Not necessarily any equations ,just systematic approaches for mesh current analysis like using KVL Also used cramer's rule The Attempt at a Solution My work: http://i28.photobucket.com/albums/c216/aldodesigns/page1.jpg...

Does anyone know how I can get part B?

Wow, thanks a lot!
