is a 12 volt system ac or dc
Direct current Most automotive applications use DC. The alternator is an AC device which uses a rectifier to produce DC. Usually 12 V DC are used, but a few have a 6 V (e.g. classic VW Beetle) or a 42 V electrical system.
Electric current The consequence of this convention is that electrons, the charge carriers in metal wires and most other parts of electric circuits, flow in the opposite direction of conventional current flow in an electrical circuit.
Standard deviation Let X be a random variable with mean value Î¼:
Classic car Cars 20 years and older typically fall into the classic class.
Vein Veins are less muscular than arteries and are often closer to the skin. There are valves in most veins to prevent backflow.
Dividend yield Its reciprocal is the Price/Dividend ratio.
