Notes on Electrostatics
These notes are meant for my PHY133 lecture class, but all are free to use them
and I hope they help. The ideas are presented roughly in the order in which they are
taught in my class, and are designed to supplement the text. I wil
Notes on Voltage, Capacitance, Circuits
Voltage
At the end of the last section we calculated the work done by the electrostatic
force when a particle of charge q is moved directly away from a xed particle of charge
Q. If ri is the initial distance and rf
Notes on Special Relativity
We start this section by reminding you what an inertial reference frame is, then
discuss how to compare the laws of physics from one reference frame to another.
Inertial Reference Frames
Imagine two space ships oating in space.

Notes on Geometric Optics and Interference eects of Electromagnetic
Radiation
We just nished discussing Maxwells Equations and the free space solutions of
electromagnetic radiation. Now we examine some practical applications for electromagnetic radiation
Exercises on Electrostatics
Exercise 1.1
Suppose you have two small point objects separated by a distance of 1 cm. Each
object has a diameter of 1 103 cm. One object has an excess of 3 1010 electrons
and the other has an excess of 2 1010 electrons on it.
Notes on LRC circuits and Maxwells Equations
Last quarter, in Phy133, we covered electricity and magnetism. There was not
enough time to nish these topics, and this quarter we start where we left o and
complete the classical treatment of the electro-magne

Exercises on Voltage, Capacitance and Circuits
Exercise 1.1
Instead of buying a capacitor, you decide to make one. Your capacitor consists of
two circular metal plates, each with a radius of 5 cm. The plates are parallel to each
other and separated by a d
