Three Methods of Electrostatic Charging

1. Three Methods of Electrostatic Charging

2. FRICTION Friction between the objects allows electrons to move from one object to the other

3. Objects charged by friction - - - + + - - - + + + + + + - + - + - + - + - -

4. CONTACT Touching a charged object to an uncharged object transfers some of the charge + + + + + + + + +

5. Objects charged by contact + + + + + + + + + + + + + + + +

6. INDUCTION A charged object is brought close to an uncharged object + + + + + + + +

7. Polarization + - + + - + + - + + + - + + + - + + This induces the electrons to move in the uncharged object.

8. Grounding + - + + - + + - - - - + + + - - + + + - + - + If contact is then provided to the ground electrons will flow onto or off of the object.

9. Objects charged by induction + - + + - - + + - + + - + This produces an object that has the opposite charge of the original charge.

10. Conservation of Charge Charges are neither created nor destroyed but are moved from place to place and object to object.
