Discussion Overview

The discussion revolves around the unexpected reading of 26 ohms on an ohmmeter in a specific circuit configuration. Participants explore the implications of the measurement and the components involved, including bulbs and a fuse.

Discussion Character

  • Exploratory, Technical explanation, Debate/contested

Main Points Raised

  • One participant questions the measurement points, seeking clarification on where the resistance is being measured.
  • Another participant states that each bulb has a resistance of 26 ohms and mentions that the fuse has a resistance of 0.3 ohms.
  • A different perspective suggests that the measurement may be influenced by the circuit being in "DEMO" mode, implying a potential alteration in expected behavior.

Areas of Agreement / Disagreement

Participants do not reach a consensus on the cause of the 26 ohm reading, with multiple viewpoints and uncertainties remaining regarding the measurement and circuit configuration.

Contextual Notes

There is a lack of clarity regarding the specific measurement points and how they relate to the overall circuit, which may affect the interpretation of the resistance reading.

why is the ohmeter showing 26 ohms here? there is virtually no path for the current to flow from the black lead to the red lead.

It is not clear to me just where your measurement points are. What is the resistance of a bulb?
 
im measuring the resistance btw the 2 black wires, each bulb has a resistance of 26 ohms, also the fuse has a resistance of 0.3 ohms.
 
Maybe it is because it is "DEMO".
