In the Physics Folder of the Science Workshop Experiment Library, open the document:

Macintosh: “P46 Ohm's Law” / Windows: “P46_OHM.SWS”

The document opens with a Scope (oscilloscope) display of Voltage (V) versus Current (A), and
the Signal Generator window which controls the Power Amplifier.

NOTE: For quick reference, see the Experiment Notes window. To bring a display to the top,

click on its window or select the name of the display from the list at the end of the Display
menu. Change the Experiment Setup window by clicking on the “Zoom” box or the Restore
button in the upper right hand corner of that window.

The “Sampling Options…” for this experiment are: Periodic Samples = Fast at 4000 Hz (set in the
Scope display using the Sweep Speed control).
