Mobile Electronics Certified Professional Quiz Correctly Answered

Voltage - Difference of electrical potential Current - Flow of electrons Rectification - Process that AC is changed into DC. Alternator - 3 phase, 6 rectifier diodes One Coulomb - 6.24 x 10 electrons Resistance - Opposition to current flow OHM's Law - E/ixr P=ixe Power - Conversion of one kind of energy into another over a period of time Law of conservation - Energy consumed by any component cannot be magically destroyed or mysteriously lost Joules - Energy required to move one coulomb (one volt) Kirchhoff’s voltage law - Voltage applied to a dc series circuit must equal the sum of the voltage drops Kirchhoff’s current law - Total current entering a point/junction in a circuit must equal the sum of the currents leaving that point Voltage Divider - Used Commonly on fords premium sound system to drop voltage for amp turn on wire. V-out=V-in x (R2/(R1+R2)) Capacitor - Opposes change in voltage Inductor - Opposes any change in current flow Air core (large/cost more) Iron core Ferrite core (cheapest) SPDT Relay - Coil, springs, contacts 150ma 86/85 coil terminals 30 common 87a N/C 87 N/O
