1 Ch Electricity Electric Charge Electric Charge Static Electricity  Conductors  Insulators  Electroscope  Transferring Charge

2 Static Electricity  Static Electricity  the net accumulation of electric charges on an object  Behavior of Charges  opposite charges attract  like charges repel

3 Static Electricity  Static Discharge  the movement of electrons to relieve a separation in charge

4 Conductors  Conductor  material that allows electrons to move through it easily  ex: metals like copper and silver

5 Insulators  Insulator  material that doesn’t allow electrons to move through it easily  ex: plastic, wood, rubber, glass

6 Transferring Charge  Friction  Objects will either gain or lose e- through friction, acquiring a + or – charge  Balloons  Socks on carpet  Car in winter  Dryer

7 Transferring Charge  By Contact (Conduction)  Touching objects can transfer charge by creating a pathway for it to flow from one object to the other  Van De Graaff generator

8 Transferring Charge  Induction  Transfer of charge without contact (objects come close to one another)  Wall  Doorknob  Van de Graaf
