Finding current in a resistor (in a big circuit)

Click For Summary

Discussion Overview

The discussion revolves around finding the current in a specific 50-ohm resistor within a larger circuit. Participants explore various methods for solving this problem, including circuit analysis techniques.

Discussion Character

  • Homework-related
  • Technical explanation
  • Mathematical reasoning

Main Points Raised

  • One participant seeks assistance in determining the current through a 50-ohm resistor.
  • Another participant asks for relevant equations that could be used to find the current.
  • Some participants suggest using Norton and Thevenin equivalent circuits or node analysis, along with Ohm's Law, as potential methods for solving the problem.
  • One participant mentions using Kirchhoff's Current Law (KCL) and emphasizes that the current entering a node equals the current exiting the node.
  • A participant reports an approximate current of 0.15A obtained through node analysis and seeks confirmation of this value.

Areas of Agreement / Disagreement

Participants generally agree on the use of node analysis and KCL as methods for approaching the problem. However, there is no consensus on the correctness of the reported current value of 0.15A, as confirmation is sought.

Contextual Notes

The discussion does not provide specific details about the circuit configuration or the assumptions made during the analysis, which may affect the accuracy of the proposed solutions.

hi,

can anyone help me with this problem? i need to try find the current in the
50ohm resistor marked with an 'x'.

any help would be greatly appreciated!

What are the relevant equations for finding that current?
 
i think it is supposed to be done my using norton and thevenin equivalent circuits or possibly node analysis? and then applying ohms law...

i do appreciate any help at all

thanks!
 
Yes, I would use node analysis in the form of Kirchoff's Current Law to solve this problem. What can you tell us about how to apply the KCL? We do not give out answers here on the PF, but we can help to point you in the right direction.
 
main point with KCL is that current into a node equals current out.I had another go at the problem with node analysis, and i got 0.15A approx, i think its right, can any1 confirm this
