Step 19: Series Opposing

To achieve a lower total voltage, we use the Series Opposing technique.
A Series Opposing technique can be achieved by
1. Connect the positive terminal of one voltage source to the positive terminal of the other voltage source.
2. Connect the negative terminal of one voltage source to the negative terminal of the other voltage source.

To determine the Total Voltage of a Series Opposing source, add all the smaller values and subtract it from the largest value.
Step 6 Diagram mistakes <br>Voltage at point A = 100V <br>Voltage at point B = 60V <br>Voltage at point C = 0V <br>
You are absolutely correct, good catch! <br> <br>Since the voltage flowing AFTER R1 (10k&Omega;) would only be a total of 100V. Therefore, <br>VR2 = (120*20)/60 = 40V <br> <br>THEN, Voltage at V2 after Voltage Drop is: <br>V2= V1-VR2 <br>V2= 100-40 <br>V2= 60V <br> <br>Correspondingly, the voltage flowing between R2 and R3 is 60V. Hence the equation must follow: <br> <br>VR3 = (120*30)/60 = 60V <br> <br>Then the voltage after passing through R3 (30k&Omega;) is: <br>V3 = V2 - VR3 <br>V3 = 60-60 <br>V3 = 0V
<p>Keep it up!</p>
<p>I thought current flows from negative to positive, not positive to negative....</p>
<p>hello sir</p><p>please post chapter four</p>
<p>very comprehensive. Thx</p>
thanks alot i'm a beginner.. waiting for chapter 4 :)
<p>thank you for your feedback.</p>
Once when you wright your set of the equations, you can calculate it online on: <br> <br>http://www.cirvirlab.com/simulation/kirch_2_real.php
geeks and company,<br><br>i have been busy with work and my car lately. my next chapter will cover parallel circuits. i should be able to publish it by the end of january.<br><br>kareen.
I have some complaints about the clip art I used and was asked to revise them to something related to electronics.<br><br>I think it is a reasonable request, so I shall work on finding relevant clipart for this chapter. I value all of your comments, questions and suggestions highly, and I take them all in consideration.<br><br>If you don't understand something and need further explanation, please don't be timid with your questions, i will try to answer them to the best of my knowledge.<br><br>Thanks, <br>Kareen
Ladies and gentlemen, I am done updating the images. You will find these images helpful in understanding the concepts introduce in this Chapter.<br><br>Thanks
