## Gauss’s Law

• Your  responses should be thoughtful, well-written, and logical. Include  visuals, equations, references, page numbers in the textbook, and links  to external websites to back up your answers as necessary. Focus on  helping your classmates understand concepts and problem solving  methodologies. I encourage clarity, insights, and analogies.

1)

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

2)

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 ?

3)

My question is how does extreme temperatures effect electric fields and magnetic fields?
