SUMMARY

The discussion centers on measuring resistance in a circuit with two resistors using an ohmmeter. The initial assumption was that the resistance measured would be 2k ohms; however, the correct total resistance is 1.67k ohms due to the parallel configuration of the resistors. The key takeaway is understanding that when resistors are connected in parallel, the total resistance can be calculated using the formula for parallel resistances, which is essential for accurate measurements with an ohmmeter.

PREREQUISITES
  • Understanding of ohm's law (V=IR)
  • Knowledge of resistor configurations, specifically parallel circuits
  • Familiarity with using an ohmmeter
  • Basic circuit schematic interpretation skills
NEXT STEPS
  • Study the formula for calculating total resistance in parallel circuits
  • Learn how to use an ohmmeter effectively for various resistor configurations
  • Explore circuit schematic analysis techniques
  • Review practical applications of ohm's law in electronic circuits
USEFUL FOR

This discussion is beneficial for electronics students, hobbyists working with circuits, and anyone seeking to understand resistance measurement in parallel resistor configurations.

The Attempt at a Solution


I am a beginner of this topic and I think it is simple as ohmmeter directly measure the resistance of the resistor which is 2k ohm while the correct answer is 1.67k ohm. I have no idea how to get it. Please help! Thanks

The schematic is sort of misleading (at least for a beginner) but if you carefully ponder over it, you ll see that the two resistances are connected in parallel (because the two ground points are essentially one, you can draw a line between the two ground points and the schematic remains equivalent), so the Ohmmeter measures the total resistance of these two resistances connected in parallel.
 
solved. Thanks a lot!
