Basic DC Theory DC CIRCUIT FAULTSOpenCircuit(Parallel)A parallel circuit has more than one path for current to flow. If one of the paths is opened,current will continue to flow as long as a complete path is provided by one or more of theremaining paths. It does not mean that you cannot stop current flow through a parallel circuitby opening it at one point; it means that the behavior of a parallel circuit depends on where theopening occurs (Figure 54).Figure 54 Open Parallel Circuit - TotalIf a parallel circuit is opened at a point where only a branch current flows, then only that branchis open, and current continues to flow in the rest of the circuit (Figure 55).Figure 55 Open Parallel Circuit - BranchRev. 0 Page 67 ES-02
