Figure 1. The current value is found by applying the equation I = (V cc − V F)/R L.To be absolutely certain of the current flow in the circuit, each LED V F would have to be measured and the appropriate load resistor specified. In practical commercial appliions, V cc is designed to be much larger than V F and thus the small changes in V F, do not affect the overall current by a large amount.

Oxidation tests on silicon carbide samples were carried out in a facility specifically developed at ONERA partly to simulate atmospheric re-entry conditions. Thermogravimetric data and surface analyses have shown the effect of low pressure and dissociated species on the oxidation of SiC. The transition between active and passive oxidation is well related to thermodynamic equilibrium between
