Part II: The parallel plate capacitor After you have drawn your electric field lines, compare your plot to the following picture: The electric field between the plates is uniform in strength (represented by upward arrows from the lower plate to the upper plate). At the edges of the parallel plates, the electric field lines start from the lower plate, move away from the plates, and then come back to end at the upper plate. In the picture above, what do you notice about the spacing of the electric field lines in-between the two plates? What does this mean about the magnitude of the electric field in-between the plates? Hook up the 3.3 V to the bottom plate and ground to the top plate. Press record and use your probe to measure the electric potential at 4 different spots along the bottom plate. What do the values read? Does the electric potential change at all as you move along the plate? If the potential difference along one plate is 0V, what does this mean about the electric field within the plate? Think about the formula for electric field
