Electric Fields and Electric Poteintal
Select a new position 2-3 centimeters from your first line and repeat steps 10-13.
Repeat step 14 until you have at least five distinct lines of different voltages.
Turn off the DMM.
Using a second colored pen or pencil, draw five or more electric field lines by connecting a line from the positive conductor to the negative conductor, intersecting with each equipotential line perpendicularly. Indicate the direction of the electric field on the drawing.

Part 2: Two Parallel Conductors
Using the scissors, cut the aluminum foil into two 14 cm x 14 cm sheets.
Fold each piece of foil in half to form a rectangle.
Note: Ensure that the shiny side of the foil is facing outward.
Fold each piece of foil again lengthwise into thirds. This should result in two long, relatively narrow pieces of foil.
Create a tab on each piece of foil by folding approximately 1 cm of one end two times. Fold the tabs such that they make a right angle with the strip. See Figure 15.
Figure caption is an adequate description of the image.

Wipe the foil strips with a paper towel so they are free of fingerprints.
Disconnect the jumper cables from the metal nuts used in Part I and remove the pins securing the nuts to the box. Set the nuts aside.
Place the foil conductors on the conductive paper such that they are parallel, centering them at .
Secure the foil conductors with 2-3 pins, ensuring that they lay flat, in contact with the conductive paper.
Attach the jumper cables to the tabs of each foil strip. See Figure 16.
Note: Ensure that the jumper cables do not touch the conductive paper.
