    Engineering How to Set Up a State Table for a 2-bit Gray Code Counter?

    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...

    What is the Norton equivalent current for terminals a and b in this circuit?

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

    What is the Norton equivalent current for terminals a and b in this circuit?

    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.

    Are My Superposition Circuit Equations Correct?

    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?

    Are My Superposition Circuit Equations Correct?

    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)?

    Are My Superposition Circuit Equations Correct?

    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...

    Nodal analysis, setting up the equations

    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
