Yes that's correct, sorry I forgot to mention it previously. And, yes, the data is in mA, not A, sorry I didn't mention that in the file either. Nope, its the regular stuff, fresh and straight from the store. Both the ammeter and voltmeter are digital, and we did a few basic labs with...

Here is a diagram of my setup: (http://i53.tinypic.com/290snc7.jpg) I attached my data in an xlx file with the graph for each trial. I connected the 150 ohm resistor to the playdoh by pushing the wire coming out of the resistor into the playdoh just under a centimeter deep and the...

Hi, I'm doing a IB Physics internal assessment on how the length of a tube of playdoh in a straw relates to the resistance of that tube. I tested it by connecting a 150 ohm resistor to one end of the tube of playdoh and connected the two to a power supply. My data at the different lengths all...
