My extended essay subject

  1. Dec 11, 2008 #1
    1. The problem statement, all variables and given/known data
    Hi, I have chosen direct current measurement techniques as my extended essay subject. I've written only 2000 words, but I am completely out of anything to write.
    I can't do alternative current, because I don't have the necessary apparatus.
    How can I expand my subject so I can fill out 4000 words?

    2. Relevant equations



    3. The attempt at a solution

    Have you talked about:

    • both voltage and current measurements?
    • resistance measurements?
    • the role of the meter's impedance (resistance) in the measurements?

    Don't forget lab tolerances and error propagation and a prologue thank you to your parents and inspirational teachers.

    Thanks, I was about to forget about those. I haven't checked the impedance either. Another question is, shoul data tables be added to the word count?

    You'll have to ask your teacher.
