Doc Physics – Parallel and Series Resistor Circuit Analysis Worked Example using Ohm’s Law Reduction

This procedure is tedious, but it requires very little fancy math and it’s conceptually beautiful. You ought to be able to look at the finished product and explain WHY the values of voltage…

    How the hell do you get 3!!!! It would be nice if you explained that part
    instead of just humming!!! HELP!!!

    You made it seem so easy! Thank you so much!!!

    I have to say, this is the best explanation of circuits I’ve ever watched.
    I’m a senior in AP Physics right now and I’ve been struggling to understand
    what was even going on, and this video broke it all down so that anyone
    could understand these complex problems. Thank you a lot and I will be sure
    to recommend your videos to all of my classmates who may be struggling.

    All i gotta say is, what a waste of paper. Next time, just flip it over!
    good video

    You are the only academic youtuber which i can actually sit through and
    watch a video that is longer than 10 minutes, and actually learn what I
    came here for plus more. Thank you SO much! <3

    The voltage drop on the 68 ohms resistor is 9.8314v

    This is great, thanks for making this video!

    You are my college physics lecture. Bless you

    Funny and Helpful! 😀 😀 😀
    Doc ftw!!!

    Fantastic! That’s the most exciting electricity lesson I’ve ever heard,
    and apparently they knew what they were talking about. Definitely
    something to follow. Makes me wonder where this guy (Dr. Schuster)

    I would have ended the video with a dollar smacking that table! BOOM!

    I did terribly in AS physics because of something that I figured out
    watching this video. Series circutis split the voltage, Parallel circuits
    split the current. If I’d have known that then it would have been so easy
    to get through the course – even more annoying is how I recall my teacher
    being unable to give a sensible answer to my question requiring that

    What an awesome way to teach! I agree 1000% with Danny MacDonald, you have
    helped me refresh for a quiz tonight, that I couldn’t do on my own, and you
    didn’t lose me once!!!! Your are witty and funny and oh so knowledgeable!
    Thanks for your input and I have subscribed to you and will definitely be
    back!! Keep up the great work!!!

    Great video, thank you.

    Ok, if you do indeed have a doctorate in physics great if you don’t then
    don’t use the title., It’s all very easy to understand if you’ve had basic
    electronics and just plain real basic if you have a degree, or are lucky
    enough to just know math and electronics.

    I am having a huge problem with VD and I can you please help me my R1 330
    R2 120 and series 150 R3 find voltage VD and from 12V at R3 my VD is 3.12
    for R3 how it is possible is spouse to be 0 at return to battery not 3.12
    not 2.868 difference. 

  21. Morgan Matchuny says:

    Thank you so much for this! I got a 100 on my test today because of your
    teaching style. Much appreciated.


    where is the one dollar?…i want it..
