CFESA electric
Voltage - answer Potential difference or driving force of electrons between two lines
Current - answer Measured in amps. Movement of electrons through a circuit when a
difference of potential exists.
Direct current (DC) - answer Circuit electrons flow in only one direction from negative to
positive.
Frequency - answer(Hertz) number of times the alternating current changes from 0 to its
peak positive then zero to peak negative then back to zero.
Power - answer Amount of energy used. Determined by voltage, current, and resistance
in a circuit.
Resistance - answer Impedance or opposition to the flow of current. Measured in Ohms.
Every circuit must have resistance.
Circuit - answera path for an electrical current to flow around
Series circuit - answerAn electric circuit with a single path. (Castle wall)
Parallel circuit - answerA circuit that contains more than one path for current flow.
(Parachute)
Series-Parallel Circuit - answerCombination of series and parallel circuits.
Continuity - answerContinuous or or unbroken path for current to flow.
short circuit - answerAccidental connection of lower resistance within a circuit.
Dead Short - answerHot touches ground or two hot lines touch.
Safety ground - answerExternal path to ground from an enclosure of an electrical
device. Used to protect people.
DC Power - answerdirect current
unbalanced load - answerCurrent is not the same on all the lines.
Kirchoff's Current Law - answerThe current that goes into a branch is equal to the
current that comes out of a branch.
