This stuff bothered me so much I had to work it all out by hand. I should have just done that in the first place. However, I didn't know about the hybrid-pi model at that time. Here is the link to the input resistance and open circuit gain for the common base, common emitter, and common...

Okay. I will tell you. That makes no sense. If you put a volt meter across those two resistors in the lab, what value do you think you would get? 20V. Even if you put the volt meter across the current source, guess what you would get? 20V. Elements in parallel with a voltage source have...

the other replies may be correct but I thought it was an interesting question. So, here's my two cents... #!/bin/csh foreach dir (`ls`) foreach file (`ls $dir`) set filetype = `awk file=$file '{if (file ~ /output_a/ || file ~ /output_b) print file'` if ("$filetype" ==...

I presume you are doing a transient analysis? Try using the step size to get a higher resolution output. Say your analysis is X seconds. Set your step size to X/500 seconds. Also, what are you trying to evaluate in your output?

your answer makes sense to me...

This might help...

So, you have two impedances hooked up to two dc voltage sources? That doesn't make any sense. If one is a cap, it will have infinite impedance. If one is an inductor it will have zero impedance.

I had to upload it to Google docs instead. I guess it was too large for this site... Thanks!

breaking from the mold... I received my midterm exam back today for electronics I. While I did set the curve, I still performed extremely poor. I wonder if some curious minds could look at my performance and shed some light on some of the critical mistakes that I made... [please see...

I will admit that your approach is correct. It is much easier to use KCL in a series RC circuit. There are many more intermediate steps if you use KVL. This will come in handy when you are dealing with higher order circuits (RLCs). In that case you have to be very familiar with the use of...

Yeah, and you have to differentiate to solve it.

You end up with a differential equation... Try it out, you'll see.

--i(t) is pieceswise continuous, you integrate over the continuous regimes --if you learn how to do it both ways now, you will save yourself a whole 'lot of *** pain later...i'm just sayin.

What about V_c(t) = 1/C integral(i(t)dt) + V_c(0) ?

Very good, now, how about KVL.
