    Finding Thevenin Equivalent with Dependent Source

    Homework Statement I am trying to find the Thevenin Equivalent of this circuit Homework Equations Using KCL and node voltage The Attempt at a Solution I found the open circuit voltage for the thevenin voltage so far by the mesh current method, and now I am trying to find the closed circuit...

    What is the relationship between resistors in a circuit?

    Hmm okay, I'll definitely look into that. Thanks everyone for the help

    What is the relationship between resistors in a circuit?

    Great, I've been working through them. What type of conversion are you talking about? I can tell it's not the same as the others

    What is the relationship between resistors in a circuit?

    Okay, makes sense. Thanks a lot for your help

    What is the relationship between resistors in a circuit?

    Ah okay I think Isee, so after that it is in series with the 42 and that combination is in parallel with the 21?

    What is the relationship between resistors in a circuit?

    Okay, but do the marker points change anything? Is 42 and 21 in series or parallel in diagram a?

    What is the relationship between resistors in a circuit?

    But does it affect the resistance between 42 and 21? Are those in series still?

    What is the relationship between resistors in a circuit?

    Homework Statement I'm having trouble trying to find equivalent resistance. Here's a picture of some circuits I am trying to simplify (http://puu.sh/ngjMC/38160c3464.png) For example, in circuit a, I can see that the 84 ohm and 105 ohm resistor are in series, and that can be simplified, but...

    How Can Work Be Negative on a Capacitor?

    Very helpful, thank you. I think i see how to go about it now, and I ended up getting a value of -1.2631 Volts. Messing with the units was troublesome, but I think I finally understand. I really appreciate your help, thanks again.

    How Can Work Be Negative on a Capacitor?

    What you're saying makes sense, but I'm now sure how to make that happen. From working out the problem, I have a voltage vs time graph that is linearly increasing until 4 micro-seconds, and then linearly decreasing from 4 to 7 microseconds. The starting voltage is at 0, and ending is at .0065V...

    How Can Work Be Negative on a Capacitor?

    I can see that shifting the voltage graph down will shift the power graph down, and at a certain point this would balance out the positive and negative portions giving me a work of 0, but I'm still confused as to how to figure out that specific shift value. What sort of formulas should I be...

    How Can Work Be Negative on a Capacitor?

    Homework Statement I am currently trying to work on the extra credit question, the capacitance of the capacitor is 2 microfarads Homework Equations W = 1/2CV^2 The Attempt at a Solution I've done the previous sections, and have gotten 4.23 * 10^-11 J as the answer for the work done on the...
