active electrodes |
Transfers concentrated electrical current into another medium (e.g., electrical current transformed into thermal energy) |
|
|
Cartesian Coordinate geometry |
Refers to the 16th-century philosopher René Descartes, who invented coordinate geometry; also called rectangular coordinate geometry |
|
|
Central processing unit (CPU) |
Silicon chip located within the computer case that is responsible for coordinating the operations of the computer, managing the computer systems, and facilitating the exchange of data with the computer memory |
|
|
Circuit |
The path that electricity travels between an energy source and its usage device(s) |

Monitor |
A visual interface for computers |
|
|
mouse |
A hand device used to move a cursor on a computer monitor and select a file or function |
|
|
neutrons |
Subatomic particles equal in mass to protons but without an electrical charge |
|
|
Patient return electrode |
New term that replaces dispersive (inactive) electrode; also called a grounding pad |
|
|
Plasma |
(1) Liquid portion of body fluid; (2) an ionized gas made primarily of free electrons and having a neutral charge |
|
|
Power |
The ability or capacity to perform or act effectively |
|
|
Pressure |
The force per unit of area; applied evenly over a surface |
|
|
Protons |
An elemental particle with a positive charge equal to the negative charge of the electron |
|
|
Switch |
A device used to open or close a circuit, thereby controlling the flow of electricity |
|
|
Power |
"the rate at which work is done" |
|
|
Power |
measured in watts |
|
|
alternating current |
describes flow of current that reverses direction periodically |
|
|
