help....

Hello,
I am doing a technical report about electrical circuits...How to create one and how to test it.
I was just seeing if anybody had suggestions on things I shouldn't forget to include in my report...

A lightbulb plugged into mains electricity is an electrical circuit. Woopee!
Test how bright it is.
Test how much current it uses.
Test the temperature of the glass on the lightbulb (ouch it is hot).
Measure how long it lasts until it burns out (boring).

If you don't want to use a lightbulb then use the motor of a vacuum cleaner instead.

I think you should title your report "help..." your professor would be impressed.
