  • Electric ChargeStatic Electricity is the accumulation of excess electric charge on an object.Click Here for a Static Electricity Example

  • Electric ChargeThis occurs when electrons are transferred from one atom to another.[http://www.school-for-champions.com/science/images/static1.gif]Click here for an Interactive Example

  • Electric ChargeAll electric charges (positive or negative) are surrounded by an electric field.[http://www.school-for-champions.com/science/images/electrical_charges2.gif]

  • Electric ChargeThese electric fields can cause other charges to move.[http://wps.prenhall.com/wps/media/objects/476/488316/Instructor_Resources/Chapter_04/FG04_07.JPG]Click here for an Interactive Simulation

  • Changing Electric ChargeLaw of Conservation of ChargeCharges can not be created or destroyed, they can only be transferred from object to object.[http://images.encarta.msn.com/xrefmedia/sharemed/targets/images/pho/t052/T052289A.jpg]

  • Changing Electric ChargeElectric charge can be transferred by contact if two charged objects are touching.This is called charging by contact or conduction.

  • [http://sol.sci.uop.edu/~jfalward/physics17/chapter8/ballandnrodcopy.jpg]Notice both end up with the same charge and repel

  • Changing Electric ChargeInduction occurs when a charged object rearranges the electrons on a neutral object.

  • Still is neutral but attracted to negative!

  • Ground

  • LightningCurrents in clouds cause charges to become separated[http://www.windows.ucar.edu/earth/Atmosphere/images/tstorm_charges.jpg]

  • LightningNegative charges in cloud induce a positive charge on the ground[http://www.windows.ucar.edu/earth/Atmosphere/images/tstorm_charges.jpg]

  • LightningWhen the charges in cloud and ground become strong enough, they attract one another causing the spark we see.[http://www.windows.ucar.edu/earth/Atmosphere/images/tstorm_charges.jpg]

  • LightningIntra-cloud lightning never touches the ground, but is 10 times more common.
