11 terms
Terms | Definitions |
|---|---|
 Electrostatic Force | The field force exerted by electrical charges; it may be repulsive or attractive depending on the kinds of charges interacting |
| Law of Charges | Like charges repel; unlike charges attract |
| Affinity | an inclination to attract or associate |
| Coulomb | SI unit for electrical charge |
| Charles Coulomb | a prominent French mathematician and theoretical physicist |
| Electrical Insulators | a material that does not easily conduct electricity; example: wool and glass |
| Electrical Conductors | the flow of an electrical current through a conductor; example metals |
| Lines of Force | Imaginary lines used to model electric and magnetic fields; Their density and direction represent the strength and direction of the field force at any point in the field |
| Field Strength | represented by the distance between the lines of force |
| Electrical Induction | Electricity generated from a changing magnetic field or a magnetic field generated by an electrical current |
| Dipole | A neutral molecule whose electrons have shifted to form positive and negative ends, or poles; example : water |
