Generation of Alternating Current
In this interactive resource adapted from the Wisconsin Online Resource Center, learn how a generator produces alternating current. More specifically, see how slip rings, brushes, an armature loop, and a magnetic field interact to produce single-phase alternating current. Animations show how positive and negative voltages are induced into the armature loop as it rotates through the magnetic field, and how the polarity of the voltage changes periodically, visualized as a sine wave.
5.5.5 Identify ways of further developing your IT skills Think about your overall IT skills and suggest areas where you feel you need to improve, based on the experience you have gained.

24.973 Advanced Semantics (MIT)
This course is the second of the three parts of our graduate introduction to semantics. The others are 24.970 Introduction to Semantics and 24.954 Pragmatics in Linguistic Theory.

24.08J Philosophical Issues in Brain Science (MIT)
This course provides an introduction to important philosophical questions about the mind, specifically those that are intimately connected with contemporary psychology and neuroscience. Are our concepts innate or are they acquired by experience? And what does it even mean to call a concept 'innate'? Are 'mental images' pictures in the head? Is color in the mind or in the world? Is the mind nothing more than the brain? Can there be a science of consciousness? The course includes guest lectures by

3 Hero and author What, if anything, does Doctor Faustus tell us about its notorious author? Having read the play, do you feel that it supports or invalidates the dominant view of Marlowe as the bad boy of Elizabethan drama? There is certainly no doubt that the play has a defiant streak, that it calls into question the justice of a universe that places restrictions on human achievement and demands the eternal suffering of those who disobey its laws. On this level, it does seem to be the work of an autho

6.4 Blogs The founder of Technorati claims that the number of 'blogs' doubles every five months and that the creation rate is approaching two per second. One estimate I read in July 2010 put the number at 400 million blogs. Because these online diaries offer instant publishing opportunities, you potentially have access to a wealth of knowledge from commentators and experts (if they blog) in a
