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 ...

To find voltage drops on Amplifier grounds, what setting should be used on the DMM while loading down and testing between the amplifier ground and the vehicles chassis ground point? - DC volts If an insufficient ground in an amplifier and is measured under load (i.e. While typical current is flowing), it will show a difference of potential between which points listed? - Between the (-) negative battery post and the (-) negative input of the amplifier Kirchhoff's Voltage Law (KVL) states...
