Pre-reading question: How strong is the electric field between two parallel plates 6 mm apart if the voltage between them is 220 V?
Aaron pointed out I squared distance when I shouldn’t have. Be on the lookout as you watch the video.
Textbook reading: “Superposition of the Electric Potential” on page 698 gives a nice summary of how to add electric potential. Also, “Conceptual Checkpoint 20-3” on pages 699-700 gives a nice visual of how voltage works.
