Cbu Phys 1204 Work And

We find precise relationships between the functions describing the electric field and the electric potential. Along the way we meet ... We find the electric potential due to two simple continuous charge distributions. The results are not important. Pay attention to the ... We see that electric interactions are reversible, and so it is possible to define an electric potential energy. We look at the general idea of a field. We then look at how, in practice, to measure a gravitational field. I then pose a question in ... We use the field due to a ring of charge to get the field due to a disk of charge. I also show how to do the integral we encountered ... We see some general characteristics that all circuits must have and start to think about electron current.

Equipotential curves are useful for visualizing electric potential and for thinking about the relationship between electric potential ... We see how to reverse the relationship to calculate fields from potentials. We start to establish a model of charge to explain why some objects interact electrically with other objects while others do not. We start to calculate some electric forces. We look at the simplest of all circuits - series and parallel circuits of resistors. We resolve the question from part 1 and come up with the definition of the electric field. Understanding this definition is crucial.

We define the electric potential, which is electric potential energy per unit charge. This is related to electric potential energy in the ...
