Procedure
PART I: Computer Setup
➀ Connect the Science Workshop interface to the computer, turn on the interface, and turn on the
computer.
➁ Connect the Power Amplifier to Analog Channel A. Plug the power cord into the back of the
Power Amplifier and connect the power cord to an appropriate electrical receptacle.
➂ Connect the Voltage Sensor to Analog Channel B. The voltage measured at Analog Channel B
will be used to calculate the current, I, which is related to the voltage across the resistor by
I
=
V

R
.
➃
In the Physics Folder of the Science Workshop Experiment Library, open the document:
Macintosh: “P51 LRC Circuit” / Windows: “P51_LRCC.SWS”
The document opens with a Scope (oscilloscope) display of Voltage (V) versus Time (msec), and
the Signal Generator window which controls the Power Amplifier.
