Carbon (Carbon-graphite) - CarboSystem

Jan 10, 2014· Carbon and graphite materials are generally manufactured in polygranular and polycrystalline form. This means that the blanks show a random orientation of crystallites. Due to this microcrystalline structure, a macroscopic blank does not show the typical anisotropic properties of a graphite single crystal.

Max Open Circuit Voltage - Miller Welding Discussion Forums

Open-Circuit Voltage (OCV) - As the name implies, no current is flowing in the circuit because the circuit is open. The voltage is impressed upon the circuit, however, so that when the circuit is completed, the current will flow immediately. I guess this means that the higher OCV available is able to provide more "work" when the curcuit is ...
