Alternating Current (AC) | current that is constantly changing in magnitude and periodically changing in direction.
Atom | the smallest particle of element that can exist without losing its identity.
Circuit | an arrangement or connection of circuit devices and components to perform a specific objective.  In its simplest form it would require an energy source, a load which would transform the energy in ...
Closed Circuit | a continuous circuit or path through which current can flow.
Conductor | a material that offers very little opposition to current flow.
Continuity | an unbroken or continuous path.
Conventional Current | the direction of flow assignment that has current flowing form positive to negative.
Coulomb | the base unit of charge, 1 coulomb is equal to 6.25 x 10(18) electrons.
Current | the measure of electron flow.
Direct Current (DC) | current of electrons that flow in one direction only.
Electricity | a fundamental form of energy.
Electron | a subatomic particle with a negative elementary electric charge.
Electron Current Flow | the direction of flow assignment that has current flowing form negative to positive.
