Transcript of Basic current electricity notes (2)
TEMPORARY SOURCES - Small amounts of
electrical power produced by Cells. (batteries)
ELECTROCHEMICAL CELL - Battery that produces
energy through a chemical reaction. (disposable)
TEMPORARY SOURCES - Continued
STORAGE CELLBattery that needs to be charged in order to
produce energy. (rechargeable)
Current Electricity: the flow of electrons along a pathway (wire) from
negative to positive.
Negative
Circuit: (from the root word circle) A pathway for electrons that ends at the
same point it starts.
Negative
Complete or Closed Circuit: A circuit in which electrons can flow and
complete the path from the negative to the positive terminal of the
battery.
Negative
Incomplete or Open Circuit: A circuit in which electrons cannot
flow and therefore cannot complete the path between the negative and
positive terminals of the battery because of openings or breaks.
2. Non-Load:(NL) An electrical device that does not use electricity and does
not have any resistance.
