| Static Electricity : | Charge: repulsion | Two separate tapes - removed from table | |
| Charge: attraction | Two tapes stuck together - removed from table and then each other | ||
| Electron Affinity aka Tribolelectric Series |
Charge transfer from dissimilar materials. Use glass, rubber, teflon rods and fur, silk, wool material. PIRA 200 : Rods and Fur |
Triboelectric Series: Table and Wikipedia |
|
| Electric Induction | Electrophorus | Electrophorus Construction : | |
| Build an electrophorus to charge by induction. Use with Leyden jar. Examples: The Physics Classroom and Brown University |

||
| Capacitance | Leyden Jar | Leyden Jar Construction : | |
| A Leyden jar is a capacitor and can store charge. The energy is stored in the electric field of the container. |

| Charge Sensor | Neon bulb: |
||
| Electroscope | Drape a light weight (Mylar) strip over a conducting mount. Bring a charged oject close to the conductor and ends of strip will separate. |
||
| Electric Field : | Electric Induction | Control a Board: Balance a board (yard stick) on a watch glass. A charged rod will induce a charge and attract board. PIRA 200 : Rods and Pivot |
Examples: Brown Univ, Purdue PIRA - Bibliography 1 and Bibliography 2 |
| Pith Ball on string, paper clip on string | |||
| Balloon: Charge a balloon sticks to stuff. |
|||
| Roll a Can: A charged rod can induce a charge and attract a can so it rolls. PIRA 200 : Charge Propelled Cylinder |
Rolling Can | ||
| Dancing Peanuts: A charged rod will attract and make objects dance. | |||
| Charge: repulsion | Electrostatic Levitation: Charge a conductive (Mylar) strip to repel and control. | Fun Fly Stick - essentialy a hand-held Van de Graaff generator | |
| Faraday Cage | Place a radio inside a conducting enclosure to exclude electric field. | Concept: National High Magnet Field Lab | |
