This is the essence of my question. Because the circuit depends on the "external loading network" is it even possible to create a thevenin equivalent that isn't a function of what you connect to it?
I get that this would be completely possible if the voltage source was dependent upon the...
But doing source transformations/simplification after you algebraically solve for the current and calculate the voltage of the dependent source should aslo work, right?
For example this algebraic example, you need to find the norton and thevenin equivalents of the circuit shown in the top...
Right but source transformations/simplification should come out equivalent to the Norton and Thevenin equivalents, which they did not. The Thevenin and Norton equivalents do not match with the actual circuit when it is hooked up to another resistor, which they should. I do not think the standard...
so when I did this problem I did nodal analysis to find the voltage across the 40k resistor, and found it to be 16V. From there I did two source transformations, combined the sources and did some equivalent resistance to get the answer as seen below:
However this differed from the answer he...

So for my solution I took the area of the plate, ((.052π) * 8.85*10-12) / .5*10-3 and I got an answer of...
So maybe I am very off in even my approach... to answer your question, if you have the same voltage across a resistor then there is no electric potential, and the resistor is effectively shorted? you can change voltage instantaneously across a resistor without damaging it, but not a capacitor or...
Homework Statement
So I am solving a 555 timer questions, and there is a resistor that is grounded on both terminals at one point. My question is what does this do to the resistor?

The Attempt at a Solution
So you need to find the voltage across node D while the capacitor is charging, so it is going to be related to the voltage of the capacitor, so a function of time, so you need to come up with the equation for Vc(t), which I...
so the equivalent resistance is just 50k? Why is the 10k shorted, or at least the capacitor sees is that way? logically speaking it seems like it should dissipate power from the battery with its placement, and have a voltage drop across it...
So do something like one of these? I don't totally understand how that will make it so you can find an equivalent resistance
So i think you are saying take out the capacitor in the second drawring, and have the two resistors be connected and then they are in parallel and that's the thevenin...

So the thing I am not sure on is how do you...
But electromagnetism is responsible for the charge of the molecules, their and their movement in the electric field. When the question asked what force was responsible for the movement it seemed like it was looking for a the general force that caused it. Especially when friction wasn't a factor...
