When the ohmmeter is connected across the open resistor, it indicates infinite resistance, or a discontinuity. Thus, the circuit open has now been located. Figure 12-171. Meter configurations during adjustments. Troubleshooting Shorting Faults in a Series Circuit An open ... fault can cause a component or system not to work, which can be critical and hazardous. A shorting fault can potentially be more of a severe nature than the open type of fault. A short circuit, or “short,” causes…

Circuit Breakers A circuit breaker is an automatically operated electrical switch designed to protect an electrical circuit from damage caused by an overload or short circuit. Its basic function is to detect a fault condition and immediately discontinue electrical flow ... Unlike a fuse that operates once and then has to be replaced, a circuit breaker can be reset to resume normal operation. All resettable circuit breakers should open the circuit in which they are installed regardless of the position…
- Chapter 12: Fundamentals of Electricity & Electronics › Basic Circuit Analysis & Troubleshooting › Troubleshooting Shorting Faults in Parallel Circuits
Troubleshooting Shorting Faults in Parallel Circuits As in a series circuit, a short in a parallel circuit usually causes an open circuit by blowing the fuse. But, unlike a series circuit, one shorted component in a parallel circuit stops current ... flow by causing the fuse to open. Refer to the circuit in Figure 12-186. If resistor R3 is shorted, a path of almost zero resistance is offered the current, and all the circuit current flows through the branch containing…
