# Current-Flow Betweenness Centrality

#### Definition

The current-flow betweenness of a vertex v is defined as the amount of current that flows through v in this setup, averaged over all vertex pairs s and t. The current-flow betweenness of a vertex v is the average of the current flow over all source–target pairs:
where n(n − 1)/2 is a normalizing constant, and I

_{v}^{(st)}is the current flow through node v between source s and sink t. Thus, current-flow betweenness measures the fraction of current flow passing through vertex v between all possible vertex pairs in the network. A simple random walk from s to t is a walk traveling from source s to target t by taking random intermediate vertices. Current-flow betweenness is shown to be the same as random-walk betweenness [BRANDES, U. 2005, NEWMAN, M. E. 2005].**See also:**Random-Walk Betweenness Centrality
