HW 7-9

Questions of the Day: (It is ok to update your cookbooks/notes from before and use them again)

• How do you solve RLC circuits using the KVL/KCL method? 
• How do you solve RLC circuits using the node-voltage method?

Reference Material:

ALL methods you learned previously for analyzing resistive (R) circuits apply the SAME way to RLC circuits using impedance (Z) instead of resistance (R).  Impedance: ZR = R ;  ZC = 1/(j$\omega$C); ZL = j$\omega$L ; $\omega$ = 2F; j = sqrt(-1) 

Today we are covering:

• Kirchhoffs laws KCL KVL.pdf Download Kirchhoffs laws KCL KVL.pdf

• Node Voltage Method Cookbook.docx Download Node Voltage Method Cookbook.docx

Other methods you can use, which we have already covered include:

• Combining Z in series and parallel Download Z in series and parallel
• Voltage and Current Dividers Download Voltage and Current Dividers

Other methods you can use with impedance (but which I won't require) include:

• Thevenin/Norton (Source transformation) Download Thevenin/Norton (Source transformation)
• Superposition
• Mesh Current Download Mesh Current

To do the MATH (I do not expect you to do this by hand):

• Use your calculator OR
• Matlab.  For example: RLC series.m Download RLC series.m
• On the exam (2014 spring, check with your professor for all other semesters!), having the correct equation will be sufficient to get full credit.
