SUMMARY

The discussion focuses on calculating effective resistance between points P and Q in a circuit involving a balanced Wheatstone bridge. The user initially struggled with the arrangement of resistors but received guidance that clarified the process. The effective resistance was determined to be 1 ohm by recognizing that two 2-ohm resistors are in parallel after removing one 1-ohm resistor. This solution highlights the importance of understanding circuit configurations in resistance calculations.

PREREQUISITES
  • Understanding of Wheatstone bridge configurations
  • Knowledge of series and parallel resistor combinations
  • Basic principles of electrical resistance
  • Ability to analyze circuit diagrams
NEXT STEPS
  • Study the principles of Wheatstone bridges in detail
  • Learn how to calculate effective resistance in complex circuits
  • Explore resistor network analysis techniques
  • Practice problems involving series and parallel resistor arrangements
USEFUL FOR

Electrical engineering students, hobbyists working on circuit design, and anyone looking to improve their understanding of resistor arrangements and effective resistance calculations.

I am facing problem with a question regarding effective resistance.I have spend many hours on this question but still can't find the answer.I have my question and my solution in the attachment follows.


Finally,I need more guidance regarding the arrangement of resistors in many ways as I am very weak at this part.Thanks for anybody that spend sometime on my question.

U DID ARRANGE CORRECTLY BUT IT SEEMS U FORGOT U HAVE TO CALCULATE RESISTANCE BETWEEN POINTS P AND Q(see the attachment)

correction

to calculate eff R b/w P n Q
u can see its balanced wheat stone bridge so u can remove one 1 ohm resistor in b/w
finally u have two 2 ohm resistor in paralle

so eff R= 2||2=1
