    Input and Output resistance(CE amplifier)

    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...

    Engineering Solve Circuit Analysis Homework: KVL, KCL, Ohm's Law

    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...

    Solving Alice's Shell Script Doubt for Comparing & Generating Scores

    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" ==...

    Simulating 30V Power Supply with Center Tapped Transformer in PSPICE

    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?

    Redrawing a Circuit in PSpice: Need 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.

    Why Did I Score Poorly on My Electronics I Midterm Despite Setting the Curve?

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

    Why Did I Score Poorly on My Electronics I Midterm Despite Setting the Curve?

    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...

    Engineering Rth of Norton's Theorem for circuit analysis

    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...

    Engineering Rth of Norton's Theorem for circuit analysis

    Yeah, and you have to differentiate to solve it.

    Engineering Rth of Norton's Theorem for circuit analysis

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

    Engineering Rth of Norton's Theorem for circuit analysis

    --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.

    Engineering Rth of Norton's Theorem for circuit analysis

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