AC is the type of current you get from wall outlets; the current switches direction \(60\) times a second (\(60\text{ Hz}\) current). With AC, we begin the study of circuits with non-linear circuit elements such as capacitors, inductors and transformers, which are the back-bone of analog and power electronics.

We are now going to explain why objects move or do not move. We do so by using the concept of force. In this chapter we consider the basic techniques of free-body diagrams, the normal force, and the forces of weight and tension.

Common conventions are to call Earth (and any conductors connected to Earth) zero Volts or to set the zero of electric potential at a distance very far away (infinity) from the charge distribution.

Diffraction effects are easier or harder to see depending on the wavelength of the wave and the size of a given opening. The physical principle behind diffraction is the same as that of interference (see Chapter 37): the superposition of waves. In order to observe the effects of diffraction, slits or gratings must be of a size comparable to the wavelength of the light.
