Data and Analysis Questions for Experiment 4:
Warning! Do NOT exceed 200 mA of current!
Doing so can damage the DMM.
Hints: Take more data points where the graphs are changing rapidly. The most interesting
part of the light bulb’s graph happens when the bulb is not yet glowing. There IS current,
but not enough to make a glow. You’ll also want to take data points more often where the
diode’s graph is changing rapidly. Feel free to add pages, use the margins, or use the back
of the page if there aren’t enough blanks in this table.
