Homework Statement Find the Thevenin equivalent of the circuit shown below Homework Equations Nothing but basic principlesThe Attempt at a Solution Alright, I realize that it will take some time for the attachement to be approved, but it's a really simple circuit. It has just one loop...

What is the most general method that can be used to get the Thevenin equivalent for a circuit (one that always works)?

Homework Statement There is a non-inverting op-amp below. http://img291.imageshack.us/img291/8242/chapter5lastproblemea1.jpg The op-amp is NOT ideal. We assume that R_i\,=\,\infty, R_0\,>\,0 and A is finite. Find the general Thevenin equivalent circuit seen at the terminals...

Hey, For the attached question, the only part I do not understand is why the Thevenin Resistance is equal to R3. I thought it would be (R1 || R2) + R3 Can somebody please explain this? cheers!

I am troubled by this question. The book for this new course seems to have different terminology then what I am accustom to. I'm stuck on this question, because I don't understand what it is asking. question) A particular signal source produces an output voltage of 30\,mV when loaded by a...

I was wondering,how do we calculate the thevenin resistance in a circuit with a load resistor?Do we remove the load?How do we calculate the voltage at the load terminals?

I was wondering,how do we calculate the thevenin resistance in a circuit with a load resistor?Do we remove the load?How do we calculate the voltage Lat the load terminals.Like for example in this circuit: http://i75.photobucket.com/albums/i281/esmeco/superpositionandthevenin.jpg I'm a bit...

In exercise i) I had to use the superposition to find the current through R2:removing the voltage source and sticking with the current source,this was my node equation: Eq: v1/1000 + v1/1000 + 0.001=0 Solving for I2 the equation was: V1-0/R2=I2 where I2=-5x10E-4 Removing the current...

Thevenin Law Woudl anyone teach me how to do question 1b? Thanks!

i have an attempted solution to a HW problem, and I want to know if it is right or wrong. Could you guys please help me out. I have attached the image as a pdf

I'm trying to find the current and voltage across R2 using thenenin. http://img209.imageshack.us/img209/4606/thv15ph.png I've managed to find Rth, which is equal to (R1 + R4)||(R3 + R5). That comes out to about 2.9 ohms. I need help with finding the Vth (Vab) though...

[SOLVED] Thevenin equivalent of a half-wave rectifier Hello folks, I'm trying to wrap my head around the process of reducing a half-wave rectifier (w/ filter) with an AC input into a simple Thevenin circuit with a DC equivalent voltage. My brain seems to be stuck in "but the input is not...

I tried every which way, but am getting a wrong answer for the Thevenin equivalent voltage in the following circuit. I tried Norton too, but got a different answer and neither of them matches the correct answer from the book. Please help me :redface: ... I'm too frustrated :( Here's the...

Sorry for such a basic question, but I'm having trouble grasping the idea of why the Thevenin equivalent of a network (as seen from two terminals) almost always has a Norton equivalent in the form in which it has been defined. More specifically, I've been trying to work out from staring at the...

Have some problems with thevenin (or my teacher is wrong, which i believe :)). http://www.fmf.nl/~wim/studie/cir1.png example from my book: Vi=15V, R1=6, R2=R3=3 Voc = Vi R2/(R1+R2) = 5 V (potential divider) R2//R3=1.5 Ohm R1+(R2//R3)=7.5 Ohm --> I = 15/7.5 = 2 A Cause R2 and...
