Ampere (A)
|
A unit of measure of the rate of current flow. One ampere equals one coulomb per second.
|
|
|
Anode
|
The positively charged structure within a voltaic cell.
|
|
|
Armature
|
The rotating part of an electrical generator.
|
|
|
Atom
|
The smallest part of an element that contains all of the properties of that element.
|
|
|
Atomic Number
|
The atomic number is equal to the number of protons (positively charged particles) in the nucleus of an atom.
|
|
|
Battery
|
A device used to convert chemical energy into electric energy. A group of voltaic cells connected together in a series or parallel connection.
|
|
|
Cathode
|
The negatively charged structure within a voltaic cell.
|
|
|
Circuit
|
An electrical path between two points.
|
|
|
Commutator
|
Strips or bars of metal insulated from each other and arranged around one end of an armature. Used to flip the flow of electricity, so positive becomes negative and negative becomes positive.
|
|
|
Conductor
|
A device or material that permits current to flow through it easily.
|
|
|
Continuity
|
The continuous flow through a component or an entire circuit.
|
|
|
Coulomb
|
6.25 x 1024 electrons
|
|
|
Current
|
A flow of electric charge.
|
|
|
Direct Current (DC)
|
Current that does not reverse its direction of flow.
|
|
|
Electromagnet
|
Magnet created by passing a current through a coil of wire.
|
|
|
Electron
|
A negatively charged particle.
|
|
|
Electron Theory
|
Electrons flow from a negative point to a positive point.
|
|
|
Element
|
The simplest form of matter.
|
|
|
Field Magnet
|
Permanent magnets, arranged outside the armature.
|
|
|
Generator
|
A device used to convert mechanical energy into electrical energy.
