Term
| Electric charge is conserved |
|
Definition
| It can neither be created or destroyed, the charge of the universe is constant |
|
|
Term
| Electric charge is quantized |
|
Definition
| It is measured in integer multiples of a fundamental chagre e=1.6E-19 |
|
|
Term
|

Term
|
Definition
| graphic mapping of the field |
|
|
Term
|
Definition
| little force needed to strip electrons, electricity flows freely |
|
|
Term
|
Definition
| requires strong electric field to cause electrons to conduct |
|
|
Term
|
Definition
| Conductivity between insulator and condutor |
|
|
Term
|
Definition
charges at rest in/on a material, producing an electric field.
-Field is zero everywhere inside a charged conductor if charges at rest
-any excess charge on a conductor is on the surface
-the elective field at the outer surface of a charged conductor is perpendicular to the surface
-excess charge accumulates at sharpest points, and is where electric field is strongest |

|
Definition
| energy necessary to move point A to point B |
|
|
Term
|
Definition
Change in potential energy per unit charge
V= Ed or W/Q (Joules/Coulomb) |
|
|
Term
|
Definition
| the energy per unit charge required to bring a positive charge in from infinity to that point |
|

|
Term
|
Definition
| Stores electric charge in the form of an electric field. |
|
|
Term
|
Definition

|
|
Term
|
Definition
| the ratio of the capacitance with a material between plates to the capacitance without any material |
