Electric Charge Notes Electric Force: attraction or repulsion between electric charges ATTRACTION REPULSION REPULSION
Electric Charge Notes Electric Field: an area (region) around a charged object where the object’s electric force is exerted on other charged object. (electric field ~ football field) see iron filings magnetic field demo
ELECTRIC FIELDS
ELECTRIC CHARGE SUMMARY RULE: OPPOSITES ATTRACT FLOW OF ELECTRICITY:
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. see balloon (static charge) demo
