There is an outline of lessons for waves in the student resources. It links all lessons, we don't go over all the material, but I think it is all worth reading, especially if you plan on going into Physics or Engineering. Friday is a quiz on magnets. Based on ideas of magnetism and the magnetism movie which has a link on the blog.

for test tuesday also note

There are two new resources to help you with electric motors and generators.

test Tuesday

Test will be on AC DC, Ohm's law V=IR and P=IV, series and parallel circuits and differences in total resistance and currents, voltages, voltage drops on a resistor in a series circuit, AC and DC generators, electric motors, the magnetic field created by electricity moving through a wire, and how a magnetic field induces current through a wire, parts of electric motor or generator, stator, solenoid, commutator, brushes, law of magnetism and how to control the direction of the magnetic force by changing poles; strengths of magnetic fields and how to create stronger magnetic fields by: more coils, more voltage, more current, less resistance, greater diameter of wire, less distance between coil and stator, Make sure to meke a mathematical relationship, is it direct or indirect, give examples. elaborate... Know how homemade speakers work or how a homemade wind turbine would work for an open response; memorize how an electric generator works, and how an electric motor works know the conversion of either kinetic E to electrical E or if it's electricalE. to kinetic energy for each. Good luck

According to The movie today and research you do at home, what are the advantages to AC electricity over DC electricity? That's it, have a great night.

study guide for Mr Worden in student resources

Note the law of charges is broken up into three parts law of charges Coulomb's law conservation of charges same ideas but more appropriately named.

Do ohm's law problem set. You should be able to do all problems now (in student resources). We will go over the conclusions and graphs from today's lab. Monday we will also let you get with partners to put together the static lab keynote, which will resemble the t=one you did at the beginning of the course.

The ohms law problem set in the student resources is due Monday and we will start it in class Friday. Problem 9 and beyond use the formula for electrical power measured in watts and use the formula P=IV
