Test on 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
