Splet"Short circuit" refers to a wire placed between two points in a circuit, usually between the two terminals of a component. For example, if you connect a wire between the two ends … SpletBut, unlike a series circuit, one shorted component in a parallel circuit will stop current flow by causing the fuse to open. Refer to the circuit in Figure 177. If resistor R3 is shorted, a path of almost zero resistance will be offered the current, and all the circuit current will flow through the branch containing the shorted resistor. cnn us asean summit
