PROCEDURE: Unit One – Diode Properties
PART I: Computer Setup
➀
Connect the Science Workshop interface to the computer, turn on the interface, and turn on the
computer.
➁
Connect one Voltage Sensor to Analog Channel A. Connect the second Voltage Sensor to Analog
Channel B.
➂
Connect the Power Amplifier to Analog Channel C. Plug the power cord into the back of the
Power Amplifier and connect the power cord to an appropriate electrical receptacle.
➃
In the Physics Folder of the Science Workshop Experiment Library, open the document:
Macintosh: “P52 Diodes” / Windows: “P52_DIOD.SWS”
The document opens with a Graph display of Current in milliamperes (mA) versus Voltage (V),
and the Signal Generator window which controls the Power Amplifier. The Current is a calcula-
tion based on the voltage drop across a 1000 ohm resistor (as measured on Channel B).
