Homework Statement

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?

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?

It's the opposite that's the real rare valuable talent out there in the big world.

You'll have to ask your teacher.
