6.002 is designed to serve as a first course in an undergraduate electrical engineering (EE), or electrical engineering and computer science (EECS) curriculum. At MIT, 6.002 is in the core of department subjects required for all undergraduates in EECS.The course introduces the fundamentals of the lumped circuit abstraction. Topics covered include: resistive elements and networks; independent and dependent sources; switches and MOS transistors; digital abstraction; amplifiers; energy storage elements; dynamics of first- and second-order networks; design in the time and frequency domains; and analog and digital circuits and applications. Design and lab exercises are also significant components of the course. 6.002 is worth 4 Engineering Design Points. The 6.002 content was created collaboratively by Profs. Anant Agarwal and Jeffrey H. Lang.The course uses the required textbook Foundations of Analog and Digital Electronic Circuits.

Waves on a string are reviewed and the general solution to the wave equation is described. Maxwell's equations in their final form are written down and then considered in free space, away from charges and currents. It is shown how to verify that a given set of fields obeys Maxwell's equations by considering them on infinitesimal cubes and loops. A simple form of the solutions is assumed and the parameters therein fitted using Maxwell's equations.The wave equation follows, along with the wave speed equal to that of light (3 x 10^8), suggesting (correctly) that light is an electromagnetic wave. The vector relationship between the electric field, the magnetic field and the direction of wave propagation is described.00:00 - Chapter 1. Background04:43 - Chapter 2. Review of Wave Equation20:01 - Chapter 3. Maxwell's Equations56:47 - Chapter 4. Light as an Electromagnetic Wave Verbally, Maxwell's equations may be summarised as follows: Electric and magnetic fields make electric charges move. Electric charges cause electric fields, but there are no magnetic charges. Changes in magnetic fields cause electric fields, and vice versa.Here are the equations in integral form: Gauss' Law for electric fields.The integral of the outgoing electric field over an area enclosing a volume equals the total charge inside, in appropriate units.The corresponding formula for magnetic fields.No magnetic charge exists: no "monopoles".Faraday's Law of Magnetic Induction. The first term is integrated round a closed line, usually a wire, and gives the total voltage change around the circuit, which is generated by a varying magnetic field threading through the circuit.Ampere's Law plus Maxwell's displacement current.This gives the total magnetic force around a circuit in terms of the current through the circuit, plus any varying electric field through the circuit (that's the "displacement current").
