I am taking an intro electrical circuits course which requires that I write extensive lab reports. I just completed a really simple lab about calculating resistance when configured in series and parallel, etc. In my intro I'm writing a short explanation about resistance, and resistors, and such. For resistors used in a common college lab course, does anyone have an idea what exact "type" of resistor they might be? I.E http://www.resistorguide.com/materials/ here are a couple examples of what I mean...I figure they might be one of the film types but I am not sure. Any suggestions are appreciated! Thank you very much!
