the hands-on portionof this lab activity, students create and measure some simple resistors (graphite andwirewound). It should be noted that the design values and measured values do not have verygood agreement for this activity; however, students can get a relative understanding of howvarious changes impact the value of resistance. Additionally, while creating the wirewoundresistors, students measure values of inductance and capacitance in addition to resistance; thiscontinues student awareness and understanding of parasitic effects, as well as introducing basicideas for minimizing them. Finally, students use an Arduino to measure the voltage across andresistance of an attached resistor. Supporting questions explore additional uses
