Homework Statement



5. What is measurement technique in impedance analyzers?
6. Draw the circuit of a two terminal impedance measurement.
7. Draw the circuit of a three terminal impedance measurement.
8. Draw the circuit of a four terminal impedance measurement.
9. How can you calculate the resonance frequency knowing values of the elements?

Homework Equations



I am given these webpages to study, but I've searched them for hours without identifying the answer.

http://en.wikipedia.org/wiki/Inductor
http://en.wikipedia.org/wiki/Capacitor
http://en.wikipedia.org/wiki/RLC_circuit

The Attempt at a Solution



I truly wish I could show a decent attempt of a solution, but the thing is that I can't even find any source answering these questions. Still I am in a desperate position to solve these questions, since I will have a test tomorrow and I can't fail a single one without failing the entire course. I've even tried to google the questions for hours without any success as well.. Thanks in advance to anybody who can help me out, I really appreciate it.

The wikipedia page on 4-terminal impedance measurement should help:

http://en.wikipedia.org/wiki/Four-terminal_sensing

I'm not familiar with a 3-terminal measurement, but 2-terminal measurement is a simplification of the 4-terminal measurement described in the wikipedia article.

And after reading the 4-terminal article, you should be able to answer question #5 now...
 
Thanks a lot guys, all the links were helpful to me! I could answer the questions now :)
