Which problem is commonly encountered during circuit troubleshooting and involves an open resistor path?

• A. Shorts Between Conductors
• B. Open Resistors
• C. Complex Circuits with a Voltage Drop
• D. Resistors in Series Circuits

Answer: (B)

An open resistor path means the circuit branch is incomplete, so no current can flow through that resistor. This is a common fault because a break—such as a damaged lead, a cracked resistor, or a bad solder joint—prevents the current from continuing through that leg. With an ohmmeter, you’d typically read very high or infinite resistance where the resistor should be, and the circuit may not operate as expected because that path isn’t contributing any current. This is different from a short between conductors, which creates a low-resistance, high-current path; a complex circuit with a voltage drop can still have functioning paths and just shows how the voltage is divided; and resistors in series circuits are a normal configuration, not a fault.
