CurrentCurrentThe rate of flow ofelectrons througha conductor.– Current ismeasured inAmperes
ResistanceResistanceAnything that inhibits or slowsthe flow of electrons through aconductor.
ResistorResistorA device thatinhibits or slowsthe flow ofelectrons throughit.
Series CircuitSeries CircuitProvides onlyone path forelectrons toflow through aconductor.
Series CircuitSeries CircuitA breakanywhere in aseries circuitwill end theflow ofelectrons or“Lights Out!”
Parallel CircuitParallel CircuitProvides morethan onepathway forelectrons to flowin a circuit.
Parallel CircuitParallel CircuitA break betweenresistors in thiscircuit will notend the flow ofelectrons.
AmperesAmperesThe rate of flowof electronsmoving past agiven point persecond (A) orAMPs
Essential LearningsEssential LearningsWhen voltage is increased(increase the number of drycells) in series and parallelcircuits, current increases.– This is called a DirectRelationship
Essential LearningsEssential LearningsWhen resistance is added in aseries circuit, the current flow isreduced or decreases andcontinues to do so as you addresistance– This is called an Inverse/IndirectRelationship
Essential LearningsIn this situation as lights areadded to the series, all thelights dim and subsequentlights may not light at all.
Essential LearningsWhen resistance is added in aparallel circuit, the current flowincreases because there aremore pathways for the current toflow– This is called a Direct Relationship
Essential LearningsEssential LearningsIn this situation, all of the lightsshould be equal in intensity
Parallel Circuit Notice how the actualdrawing differs from thediagram. Notice the straight linesand right angles atintersections You will use the zig-zagsymbol for your diagramsand a broken line for eachswitch.
Exit TicketCompare and contrast a parallelcircuit to a series circuit.
