AC/DC Electronics Laboratory 012-05892A

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).
