    How to setup KVL equations with element laws?

    It is getting clearer and I was able to get several examples correct today, but I am somewhat stumped with this one.. mainly because I don't know how to treat a system with two sources like this. So I started - label branch variables, assemble element laws (resistors v=ir, v source = v...

    A temporary goodbye

    Lots of luck to you in your travels, stay well! There are lots of well developed areas in South Africa, where will you be staying?

    How to setup KVL equations with element laws?

    Thank you Steve for taking the time to write that all down!! It is greatly appreciated. The associated variables concept, I understood once I put it in perspective that the positive and negative they were assigning was arbitrary - I imagined that I was probing the circuit with a dmm and if the...

    Today's eBay purchase

    LOL, now the hard part as you wait for the slow boat from china to come in ;-) My recent experience has been about 8-14 days.

    You did really good on that! Did it take you long to find all that under one seller?

    V-Reg Board for Breadboard use

    Finally got all the components to make the v-reg board. The made a few modifications to the schematic - 1. since I only had 1/4w resistors, I placed two in series to handle the dissipated power through them and I put in some pins to interface the board to my breadboard. Should make powering low...

    How to setup KVL equations with element laws?

    Indeed, but that doesn't help me figure out what went wrong or where.

    How to setup KVL equations with element laws?

    6.002x is great! I understand the concept and things are actually starting to make sense!!! Too bad I can't keep up with the math :eek: I've read over 70 pages of the text, watched a few hours worth of videos and some independent research and have concluded that I am fairly thick :rolleyes::D...

    Stranded Hookup Wire and Logic Circuits?

    LOL, fuzzy indeed. Good point on the stranded solder joint, I hadn't thought of that.

    Stranded Hookup Wire and Logic Circuits?

    Dave, I understand the stranded for connections between items that may move, but why solid links on the board? Preference or other reasons? Thanks!

    Stranded Hookup Wire and Logic Circuits?

    Thanks all, I didn't think it was founded, but never hurts to check. I saw it referenced on a review for hookup wire from radio shack.

    Stranded Hookup Wire and Logic Circuits?

    I wanted to buy some hookup wire for further experimentation and came across a review stating that it was not a good idea to use stranded wire for logic circuits. Is there any truth to this? I was thinking of buying some 22 ga. stranded wire as it would be more flexible than solid core. I...

    How Transistors Work

    I really appreciate that Adam :D I didn't realize how many great resources for learning electronics there are on the web, including this site with its great members. I will do my due diligence first before asking, but expect many questions!

    How Transistors Work

    I have no intention :D I enjoy electronics and have since I was young, now that I have my own, I think its important that they get involved as well. If it takes me 10 years, that will be fine, they will be teenagers by then, but I should think along the way they will get a darn good education!

    Twin LED Flasher

    It's good advice Adam! And Kris has cautioned me on this as well. I want to know it all!! LOL. I will be very happy to be able to make things work on my own and certainly quite happy to have you fine gents help me along. :) I should think though one would need to know at least conventional...

    How Transistors Work

    Safe travels, I look forward to your continued input - all of your inputs! It's certainly a bit on the deep end for me, but I love to learn and perhaps in time all of it will make sense. For now, the equations are still foreign.

    Twin LED Flasher

    You are quite right Adam, a resource on this would be aces! If I understood where the flow goes and how it should move, I would feel more comfortable making black box assumptions when the charge reaches components.

    How Transistors Work

    On a conceptual level I can follow along. Knowing when to use certain equations and how to find the information from the data sheet seems to be the problem for me. It will require more experience and exposure for it to make sense and I certainly do appreciate your help!
