This isn't a homework question... I'm just trying to understand Mosfets in general. I've been reading about them, and I find them really interesting- very cool. However, I don't understand how the Vgs = Vds if the mosfet itself has resistance!? For example, I found this in a text and I fail to...

Awesome :) thanks for your response :)

Homework Statement See attached for a view of the problem Variables a=transformation ratio= 1/5 Ip=2Amps ZL=2 ohm resistor Homework Equations Q1 : Find the current magnitude of the current IL and the Voltage VL Q2 : Find the input impedence. The Attempt at a Solution OK, my...

I agree with your asesement :) I think I just thought the teacher was asking a trick question per say. Like, if there is no change in time, and only considering 9uSeconds, and not the change in slope- what would the voltage equal... Thanks for the responses :)

I have studied calculus. I was originally a math and physics major some years ago- never finished though. Left college, and I'm back now to finish my degree in engineering. I really love college/engineering- glad I'm back :) I just sort of regret signing up for this summer class. It...

Thanks for the response :) I'm attaching the orinal problem to this post. I guess the point that really threw me with the question, is that it only referenced a single point in time, where you would normally obtain the slope of the line, based upon a series of point. I just regarded the...

Ok, this was not a homework problem, but a question I had on a test for electrical engineering. The question was as follows; "What is the inductor voltage at 9uSeconds." Ok, the way I approached the problem, and was marked as being wrong. I said that I know the equation for an inductor is...

Ok, I figured out the answer... you need to work backwards, as follows; Original Equation --- > AB + (A' + B')C + AB STEP 1: AB + (A' + B')C + AB STEP 2: AB + (A' + B')C <--- AB+AB=AB, so one AB is removed STEP 3: AB + (AB)'C <--- On this step you took a step backwards Step 4...

Homework Statement AB + (A' + B')C + AB Homework Equations I've simplified many problems, but this one is giving me trouble. I know the answer is AB + C, but for some mental reason, I can't seem to come to that answer. The Attempt at a Solution STEP 1: AB + A'C + B'C + AB...
