CFESA ELECTRIC EXAM QUESTIONS
AND ANSWERS 100% CORRECT.
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 - ANSWERAmount of energy used. Determined by voltage, current, and
resistance in a circuit.
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.
Kirchoff's Current Law - ANSWERThe current that goes into a branch is equal to the
current that comes out of a branch.
What 3 things to know about contactors - ANSWERCool voltage
line voltage
amps
short circuit - ANSWERAccidental connection of lower resistance within a circuit.
Voltage - ANSWERPotential difference or driving force of electrons between two lines
unbalanced load - ANSWERCurrent is not the same on all the lines.
Resistance - ANSWERImpedance 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)
Current - ANSWERMeasured in amps. Movement of electrons through a circuit when a
difference of potential exists.
Direct current (DC) - ANSWERCircuit electrons flow in only one direction from negative
to positive.
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.
