Thank you very much! I will try that!

I think I get the fist part of the question, but I am stuck on getting an expression for the current in terms of voltage for the second situation where we add a resistor.

Thank you for the reply! I do know how to solve the expression for the current through the diode and invert it to get vD. My problem is that I need to get an expression of the current in terms of voltage. Since it is not linear, I am not sure how to do that. I have not used Newton's method to...

Helo, I am in an electronic course and we just started studying diodes. I am stuck on the following problem: Place a 100 ohm resistance in series with a diode, and plot current versus voltage across the series combination. I am also given the following values for the diode: n = 1, Is =...

Hello! I am trying to write a program that solves the Schrödinger Equation for a particle in an infinite square well. I did a lot of research regarding the methods that could be used to accomplish this. I am writing this program in Matlab. The method I am using is called the Shooting Method. In...

Thank you!

Thank you very much for this explanation! I really appreciate it!

Would the current not choose the path that has a voltage drop, which is the one with the resistor?

Thank you for the note. I changed the title of the thread.

I think I am starting to understand where you are coming from. Initially, I thought that current would not go through the parallel piece of wire because there is no voltage drop there, but it would go to the resistor because there there is a voltage drop and the current could flow. I have always...

So, I think that I am misunderstanding the problem. The arrow on the switch in the diagram means that the switch was closed for a long time and then it was opened at t=0s. If this is the case, then would that not mean that the capacitor was charged at t <= 0?

Thanks you for the quick reply! Oh! I I did not think of it this way. My answer would be "No, it would not." That raises another question that might be related to a fundamental piece of information that I don't know. Current would also not flow if there was no change in voltage, which the...

Thanks a lot!

Thank you very much! Sorry for the late reply, but I had to sleep on it. It worked perfectly fine! I was inventing my own incorrect rules for calculus, and that did not work very well! P.S. I was wondering how you were able to type those derivatives very clearly. It is much more clear than...
