What does it mean if a DMM set to continuity mode does NOT beep when connected to a circuit?


AThe circuit has a resistance between 25 and 250 ohms.
BThe circuit is open, or its resistance exceeds 250 ohms.
CThe circuit is complete and has acceptable continuity.
DThe circuit has low resistance and is functioning properly.

Verified Answer :

Final answer:

If a DMM set to continuity mode does not beep, it indicates that the circuit is likely open or has a resistance exceeding 250 ohms. This means that there is a break in the circuit or a high resistance preventing current flow. The correct answer is B: The circuit is open, or its resistance exceeds 250 ohms.


Explanation:

Understanding Continuity Mode in a Digital Multimeter

A Digital Multimeter (DMM) set to continuity mode is used to check whether there is a continuous conductive path in an electrical circuit. If the DMM does not beep when connected to a circuit, it usually indicates a specific condition regarding the circuit's integrity.

If there is no beep, it typically means that:

  • The circuit is open, or
  • Its resistance exceeds 250 ohms.

In practical terms, an open circuit means that the flow of current is interrupted. This could be due to a break in the wire, a disconnected component, or a faulty switch.

And regarding resistance, if the resistance of the circuit is very high (greater than 250 ohms), the meter will not complete the circuit internally to allow a current to flow, hence no beep will be heard.

Therefore, the correct answer to the question would be:

Answer Choice:

B) The circuit is open, or its resistance exceeds 250 ohms.
