Well - probably the most basic test instrument would be a VOM/DVOM - and you could expand into a discussion of Ohms Law (P/IE). You can also use an Oscilloscope to trace circuits - or if you want to analyze a DC circuit for RF generation you can use a frequency counter/analyzer ...

That should give you a couple of things to research ...

I researched what you told me and i found out about burden voltages for DMM's and analog meters. Also pulse generators

Since a VOM (analog volt-ohm meter) or DVOM (digital VOM) is probably the most basic test instrument - why not just a paper on it's theory of operation?

1) How does it measure voltage?
2) How does it measure resistance?
3) How does it detect the current flow? (the meter goes +/- based on where you put the red and black leads)

Here is the link to the Wikipedia page for Multimeters.

That should easily give you two pages for your paper.

i pretty much did a whole page on meters. I mostly talked about the moving coil operation. Now i just need to think what to write on pulse gereators.
