A wireless sensor network can get separated into multiple connected sensors. But some nodes are failure due to mechanical, electrical problems, environmental degradation battery depletion or hostile tampering. Which is called a \"Cut\". In this paper, the problem of detecting cuts by the remaining nodes of a wireless sensor network. The authors propose an algorithm that achieves. The algorithm works based on an imaginative \"Electrical potential\" of the nodes which is an iterative method and the convergence rate of the scheme is independent of the network.
