8. Designing a Series Circuit

A series circuit is a a circuit with just one path for current to flow.

In a series circuit:

1. Resistance is additive

2. Current is constant

3. Voltage drops are additive

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 (10kΩ) 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 (30kΩ) 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
