Describe three phase current
WebThe wetting of rough surfaces and the three-phase contact line are complex and vary according to the dimensions of the roughness and its spatial heterogeneity. The results documented in this thesis show that the apparent contact angle varies around the periphery of the water droplet due to the roughness of the surface on the first contact. Also, … WebGustav Kirchhoff’s Current Law is one of the fundamental laws used for circuit analysis. His current law states that for a parallel path the total current entering a circuits junction is exactly equal to the total current …
