Gauss’s Law can be used to find D dot ds (using the integral form of Gauss’s Law) or electric field flux flowing out of a volume through surface S, where the total flux through the surface equals the enclosed charge, Q. If the conveniently chosen Gaussian surface is a circle to enclose a positive point charge, it stands to reason that the direction of D is radially outward. Reading closely, it also allows you to pick a “purely tangential” component. I had not thought about the tangential component. I cannot visualize what surface allows flux to be radially outward and tangential. This is discussed on page 188 of our text. Thanks for any insight, Kyle
What kind of circuits are used to wire houses and have more than one path for electrons to flow? What will happen if we use the alternate circuit ?
My question is how does extreme temperatures effect electric fields and magnetic fields?
