SUMMARY

The discussion focuses on solving resistor circuits by working backwards to determine the current through specific resistors. The user has established that the current in resistance R6 is 1.4A and provided values for resistances R1, R2, R3 (2.00 ohms each), R4 (16 ohms), R5 (8.00 ohms), and R6 (4.00 ohms). The user is seeking to compute the ideal voltage of the battery using systems of equations and the reduced row echelon form (RREF) feature on a calculator. The conversation emphasizes the importance of understanding voltage in parallel and series circuits when analyzing resistor configurations.

PREREQUISITES
  • Basic understanding of Ohm's Law
  • Familiarity with series and parallel resistor configurations
  • Knowledge of systems of equations in circuit analysis
  • Experience using RREF calculators for solving equations
NEXT STEPS
  • Learn how to apply Kirchhoff's laws in circuit analysis
  • Study mesh analysis for complex circuits
  • Explore the use of simulation software like LTspice for circuit design
  • Investigate the impact of different resistor values on circuit performance
USEFUL FOR

Electrical engineering students, circuit designers, and hobbyists looking to deepen their understanding of resistor circuits and voltage calculations.

Problem: I have found the total current running through the entire circuit. My problem is now I am trying to work backwards to determine the current through a certain resistor. I know when dealing with basic capacitors, voltage in parallel is the same, and charge in series is the same. Does the same apply to working with a circuit that only involves resistors?

Thanks.

I believe I found the correct way to do this. It would have helped if I was approaching the problem a different way.
 
Welcome to MHB, csmith23! Could you please post a picture of the problem that's not hidden behind a password? Or type up the problem statement?

Thanks!
 
I think this is the same as http://mathhelpboards.com/other-advanced-topics-20/mesh-currents-emfs-resistances-10968.html.
