Electric Field Mapping—
Demonstration Kit
By: The Flinn Staff
Using a conductive pen, simply draw any type of charge configuration onto conductive
paper. By measuring the voltage at different locations between the charges,
you can determine lines of equal potential and then draw in or “map” the electric
field lines as well. Amazing! Find the field between a dipole, charged plates or a
quadrupole, or even measure the charge of an electric field during a thunderstorm!
Note: A power supply or 6-V battery, voltmeter and connector cords are required and
available separately.
Catalog No. Description Price/Each
AP7282 Electric Field Mapping—Demonstration Kit $127.00
AP5375 Power Supply, Multiple Voltage Battery Eliminator 111.00 Orion Science
Orion Science Equipotential Lines Kit
Explore equipotential surfaces and lines by mapping an electric field with this kit
from Orion Science. Both the power supply and the voltmeter are conveniently built
into the case, which doubles as storage for the components when not in use.

I just wanted to thank everyone at Flinn for all that you do to support those of us who teach
science. These resources are a huge help. Thanks for helping us look into ways to reach
our students with real science.
