Unknown Voltage Source and Current

Click For Summary
SUMMARY

The discussion focuses on determining the voltage across a 9.1-ohm resistor in a circuit. Participants suggest using nodal analysis or loop equations as effective methods for solving the problem. A previous thread contains a step-by-step solution that is recommended for further understanding. The emphasis is on revisiting established solutions to clarify the current issue.

PREREQUISITES
  • Understanding of Ohm's Law
  • Familiarity with nodal analysis in circuit theory
  • Knowledge of loop equations for circuit analysis
  • Basic concepts of electrical resistance
NEXT STEPS
  • Review the previous thread on nodal analysis techniques
  • Practice writing loop equations for simple circuits
  • Explore advanced circuit analysis methods using Kirchhoff's laws
  • Learn about voltage dividers and their applications in circuits
USEFUL FOR

Electrical engineering students, circuit designers, and hobbyists looking to enhance their understanding of voltage and current in electrical circuits.

clue: what's the voltage on the 9.1 ohm resistor? then just keep going.
 
Pantera, if you look closer https://www.physicsforums.com/showthread.php?t=159391" You might notice that I already solved a similar problem for you. I even did it in a step by step ;) So, I guess that you've to go back to the original thread and read it one more time, because the solution is there, you just can't see it. So take a better look ;)

You can either solve it by applying nodal equations as I did for you in another thread, or you can write two loop equations the describes the circuit.
