Potential Distribution on Random Electrical Networks
  Let $G=(V,E)$ be a random electronic network with the boundary vertices which is obtained by assigning a resistance of each edge in a random graph in $\mathbb{G}(n,p)$ and the voltages on the boundary vertices. In this paper, we prove that the potential distribution of all vertices of $G$ except for the boundary vertices are very close to a constant with high probability for $p=\frac{c\ln n}{n}$ and $c>1$.
