Electric Charge and Electric Field Static Electricity – Unmoving charge Two types Positive – lack of electrons Negative – excess electrons Like charges - Repel Opposite Charges - Attract Electric Charges Charge can be induced by rubbing an object – View demonstrations Charge is detected using an...
Section 20.1 Electric Charge and Static Electricity Electric Fields Def.-the effect an electric charge has on other charges in the space around it Key Concept: The strength of an electric field depends on the amount of charge that produces the field and on the distance from the charge. Figure...
The integral\color{royalblue}{(1.6)}is not always the most suitable form for the evaluation of electric fields. Gauss's law is another integral result which is sometimes more useful. Figure 1.1: Gauss`s Law For a single point charge: \begin{equation} \oint_{S} \mathbf{E}\cdot\mathbf{...
