v This module will help you learn what Ampere's Law is and how to use it to calculate the magnetic field given the distribution of electric current. After finishing you will know how to choose an appropriate Amperian loop, and know how to use Ampere's law physically and mathematically.

v In this module you will learn many of the physical characteristics of electric fields. By the end of the module you will understand how electric field is defined by the electric force on a charge, that electric field is a vector, an electric field is produced by a charge or a distribution of charges, and how the magnitude and direction of the field depend on the geometry of the distribution of sources. You will learn to display electric fields and examine their geometric properties, understand how field lines represent the strength and direction of the field. Given an electric field, you will be able to deduce the presence and relative magnitudes of hidden charges producing it.

vThe problem of creating a vector field as a gradient of a scalar function is illustrated in Electrostatics. Starting from the electrostatics of a single point charge, students are led through a series of exercises, to the study of electrostatics of a more complex assembly of point charges and continuous distribution of charges.

v This module will help you understand how a circuit with an inductor and a capacitor undergoes an electromagnetic oscillation, and how the period and frequency of an oscillation depend on the inductance and capacitance. You should also finish with an understanding of how the energy in a circuit is conserved if there is no resistance.

v After completing this module you will know what Gauss's law is, including when and how to use it, how to select a useful Gaussian surface, and be able to use Gauss's law physically and mathematically

v Once you have completed this module you will understand that a changing magnetic field gives rise to an electric field, and what magnetic flux is, how it is related to magnetic field, and how it is different from magnetic field. Furthermore, you should understand Faraday's Law of electromagnetic induction, and Lenz's Law and its importance to induction. You will be able to determine the circulation of the electric field (EMF), and understand its physical meaning

v This module will help you understand what electrical current and resistance are, the relationship between voltage, current, and resistance. You will also be able to calculate these quantities for resistors in a circuit, the resistance of a network of resistors, and the resistance of a resistor given its size and shape and the resistivity of its material.
