6. ELECTRIC CHARGE SUMMARY
RULE: OPPOSITES ATTRACT
FLOW OF ELECTRICITY:

7. Types of Electricity Notes
Current Electricity: flow of electrons
AC (alternating current) electricity
DC (direct current) electricity
Static Electricity: stationary electrons; charge build up of electrons on an object but they do not flow continuously.
