Document Summary
By the end of this unit, you should be able to: Explain what is happening at the atomic level when a current of electricity flows. Describe the meaning and units of charge, current, field and potential. Define resistance and resistivity and explain how they differ. Explain the rules for the series and parallel connection of resistors. Describe the basic chemistry of simple batteries. Developed later than mechanics because most matter in bulk displays displays no obvious effect of electric charge. Know now that electric charge exists in two forms, positive (+) and negative (-), and matter normally contains equal amounts of both, producing a null effect. Like charge repel (++ or --) and unlike charges attract (+-) In the 20th century, as the structure of the atom became better understood, it was realized that the electric neutrality of bulk matter was the result of several facts:
