    Does every object have capacitance?

    Does every object have a capacitance associated with it? For example, is there a capacitance in a single wire or a chair? If so, can you please explain why because I was taught that capacitance is associated with two conducting objects. Thank you.

    Question about charge by induction

    Say you have two conducting spheres separated by some distance. One has a certain positive charge and the other is attached to ground and has no net charge at first. 1.When the second sphere is charged by induction, does it gain the same amount of net charge but of opposite sign as the...

    Schools Need some advice on how to be successful in college

    I am currently a sophmore electrical engineering major. It is very important to me that I both learn the material that is being presented and to get good grades. I know that to do these things one must study and study hard. However, I find that there are only a few times during the day during...

    Conceptual question about torque

    Imagine an object in space with no other forces acting on it. Why is it that if you apply a torque on the object, it will rotate around its center of mass? That is, why does it "choose" to rotate around the center of mass? I can't come up with an answer and this question has been bugging me for...

    Feynman's description of angular momentum

    I meant that does the equation dA/dt=L/2m hold in general where da/dt is the areal velocity.

    Feynman's description of angular momentum

    I recently watched the Feynman Messenger Lectures on project tuva. I hope some of you have watched the second video lecture in the collection or will watch it in order to help me with my following question :smile:. In this lecture Feynman talks about angular momentum in terms of the time rate of...
