WebMay 6, 2024 · The articled explained that a typical Red LED has a voltage drop of 1.8 V and a current of abound 25mA and Arduino Pin has an output of 5V. Using these values and the formula from the article, the calculation is. V = (power source) - (Voltage Drop) = 5V - 1.8V = 3.2 V I = 25 mA. so R = V/I. R = 3.2/0.025 = 128 Ohms. Which is not equal to 220 Ohms. WebJun 22, 2024 · In this paper, the interfacial adhesion work (Wad), tensile strength, and electronic states of the Fe-amorphous Na2SiO3-Al2O3 and Fe-Al2O3 interfaces are well-investigated, utilizing the first-principles calculations. The results indicate that the Fe-amorphous Na2SiO3-Al2O3 interface is more stable and wettable than the interface of … bly171d

Teertstra; Engineering. 2004; The exposed surface area of many of today's high powered electronic packages is no longer sufficient for the removal of the heat generated during normal operation. Heat sinks are a commonly-used, low … WebShear resistance of the steel-concrete interface can be evaluated by either elastic or ultimate strength procedures; both methods have shown good correlation with the test results. The interface shear force resulting from superimposed loads on the composite joist may be computed, using the "elastic approach", by the well known equation: bly225
