Electric Fields/Electric Potential

  • #1
I have a few questions about how to find the magnitude of an electric field.

1) I need help with plotting the electric field after I have calculated the magnitude of the electric field on a graph, depicting in which direction the electric field is.
2) I also need help with just electricity in general. I could really use a good study guide or outline/review on electricity. I have the the Giancoli AP Physics sixth edition book (if needed).

Thanks everyone,

Welcome to PF

1. The direction of the electric field is the direction of the force experienced by a small positive test charge. The direction should drop out of the magnitude calculation.

2. That is very general indeed.
quick overview:

... the description changes a lot with your level.
Giancoli is primarily for pre-med: you more bio-oriented?

usually the "electricity" topic covers electric circuits and currents, while the "electromagnetism" topic covers fields and charges. Some courses treat magnetism separately.
