A fantastic lab to show the relationship between voltage, current and resistance. Students will easily make the comparison between brightness of a lightbulb and the amount of nichrome wire between the clip leads of the circuit. Students will also “feel” the change in the electric circuit’s resistance when they power it with a hand generator. Verify Ohm’s law quantitatively by connecting a voltmeter and ammeter to the circuit. Includes 470 mm of nichrome wire mounted on a wood base, wire lead with lightbulb socket and alligator clips, miniature lightbulb and one piece of replacement nichrome wire.
