Units 7 - 10 Unit 7 is a nice break for you. The calculations are minimal and the material is very straight forward. Batteries are an area where we could spend a whole course, but unfortunately we must cover them in a single unit. Please take time to explore the web for more information on batteries. It has been my experience that battery manufacturers usually have very informative web sites. Unit 8 will introduce you to the world of magnetism. We all played with magnets as a child, now you will have an opportunity to understand how they work. Unit 9 is a continuation of magnetism. Inductance is based on a magnetic field and is the natural topic to follow magnetism. Pay close attention to what determines the amount of inductance an inductor has. That will give you insight into how they work. We see the effects of inductance everywhere, it will be very useful for you to understand it. Unit 10 will introduce you to the capacitor. It is truly amazing how two parallel plates separated by a non-conductor can generate an electric field between them. Hmmm, almost sounds like two parallel wires separated by air or two traces on a printed circuit board. Could these be modeled as capacitors? This unit will answer that question and more. |
