After checking a receptacle with an ohmmeter, what should the meter indicate between specified points if the leads are correctly placed?

• A. A finite value
• B. 0 ohms
• C. An infinite value
• D. A variable resistance

Answer: (C)

When checking a receptacle with an ohmmeter, the meter should indicate an infinite value between specified points if the leads are correctly placed. This situation is typical when testing for continuity on a circuit or device that is powered off. An infinite reading suggests that there is no electrical connection between those points, which indicates an open circuit. In the context of receptacles, this reading is crucial for safety and proper function—if there is an infinite resistance, it confirms that the circuit is not completing, thereby preventing potential electrical hazards. Conversely, reading a finite value or 0 ohms would imply a short circuit or a direct connection, which could present unsafe conditions. A variable resistance reading would indicate some degree of instability or an unexpected condition in the circuit, which is not typical in a properly functioning receptacle test. Therefore, the expectation of an infinite resistance reading helps ensure that the receptacle is functioning as intended and that it is safe to use.
