|---|---|---|---|---|---|
| Electrostatics | The study of electric charges at rest.
🗑
|
||||
| Electrical Force | A force that one charge exerts on another. When the charges are the same sign, they repel; when the charges are opposite, they attract.
🗑
|
||||
| Charge | The fundamental electrical property to which one reaction event stimulates one or more additional reaction events to keep the process going
🗑
|
||||
| Conservation of Charge | The principle that net electric charge is neither created nor destroyed but is transferable from one material to another.
🗑
|
||||
| Coulomb's Law | The relationship among eletrical force, charges, and distance: The electrical force between two charges varies directly as the product of the charges and inversely as the square of distance between them.
🗑
|
||||
| Coulomb | SI unit of charge. One coulomb (symbol C) is equal to the total charge of 6.24 X 10 to the 18th electrons
🗑
|
||||
| Conductor | (a) Material through which heat can be transferred. (b)Material, usually a metal, through which electric charge can flow. Good conductors of heat are generally good charge conductors.
🗑
|
||||
| Insulator | (a) A material that is a poor conductor of heat that delays the transfer of heat. (b) A material that is a poor conductor of electricity.
🗑
|
||||
| Semiconductor | Material that can be made to behave as either a conductor or an insulator of electricity.
🗑
|
||||
| Induced | Term applied to a voltage, electric field, or magnetic field that is created due to a change in or motion through a magnetic field or electric field.
🗑
|
||||
| Induction | The charging of an object wothout direct contact.
🗑
|
||||
| Grounding | Allowing charges to move freely along a connection between a conductor and the ground.
🗑
|
||||
| Electrically Polarized | Term applied to an atom or molecule in which the charges are aligned so that one side is slightly more positive than negative than the opposite side.
🗑

Review the information in the table. When you are ready to quiz yourself you can hide individual columns or the entire table. Then you can click on the empty cells to reveal the answer. Try to recall what will be displayed before clicking the empty cell.
To hide a column, click on the column name.
To hide the entire table, click on the "Hide All" button.
You may also shuffle the rows of the table by clicking on the "Shuffle" button.
Or sort by any of the columns using the down arrow next to any column heading.
If you know all the data on any row, you can temporarily remove it by tapping the trash can to the right of the row.
