Note
The most convenient combination of interface and sensors for use with the Thermoelectric circuit
board is:
• PS-2001 PowerLink interface
• PS-2143 Quad Temperature Sensor
• PS-2115 Voltage/Current Sensor
• PS-2135 Fast Response Temperature Probes (3-pack), optional
This is the equipment called for by the experiments in this manual and on the CD-ROM. There are
other options for PASPORT

sensors and interfaces, and stand-alone
multimeters. Please contact Tech Support, or see the PASCO catalog or website for details.
Introduction
The Energy Transfer–Thermoelectric circuit board provides students with a hands-on example of
a thermoelectric heat engine. Using measurements from temperature, voltage and current sensors,
students will quantitatively study the energy, work and heat flow associated with heat engines,
heat pumps and refrigerators.
This manual includes instructions for five experiments with sample data and teachers’ notes. You
can photocopy the student instructions or print them from the editable copy of this manual
included on the CD-ROM. Experiment #5 is a DataStudio workbook, which contains the student
instructions within the DataStudio file.
In addition to the experiments detailed here, the Thermoelectric board is well-suited for self-
guided exploration. The following sections will familiarize you with the components of the
experimental set-up.
