Electric Charges and Fields

Topics in this chapter

1. 1Electric Charges and Fields: Chapter IntroductionA rubbed comb lifts paper bits without touching them. Rubbing moves electrons, a charged body attracts even neutral paper by induction, and every charge reaches out through its electric field. Watch
2. 2Electric Charge: Like Charges Repel, Unlike AttractThose sparks when you pull off a sweater come from electric charge. How rubbing moves electrons, what positive and negative mean, and why like charges repel. Watch
