Much of modern technology involves devices that
function using electric currents. Electric current is a
certain type of flow of electric charge, but not just any
movement of el

In the previous chapter we discussed the field concept, and
in particular electric fields. The picture of an electric field that
emerged is that of a collection of arrows, one for each point
Chapter 14: Oscillations
Oscillations are back-and forth motions. Sometimes the word
vibration is used in place of oscillation; for our purposes, we can
consider the two words to represent the same class of motions.
In the ideal case of no friction, free
