Which Two Resistors Are Parallel in This Circuit?

Click For Summary
SUMMARY

The discussion focuses on identifying parallel resistors in a circuit to simplify it into a single equivalent resistor. The resistors involved are R1=2Ω, R2=5Ω, R3=13Ω, and R4=8Ω. The correct approach involves using the formulas for equivalent resistance in parallel (1/R1 + 1/R2 = 1/Req) and in series (R1 + R2 = Req). The user successfully determined the parallel resistors and proceeded to redraw the circuit accordingly.

PREREQUISITES
  • Understanding of electrical circuit diagrams
  • Knowledge of equivalent resistance calculations
  • Familiarity with series and parallel resistor configurations
  • Basic algebra for manipulating equations
NEXT STEPS
  • Study the concept of equivalent resistance in more complex circuits
  • Learn about Kirchhoff's laws for circuit analysis
  • Explore the use of circuit simulation software like LTspice
  • Review practical applications of resistors in electronic devices
USEFUL FOR

Students in electrical engineering, hobbyists building circuits, and anyone looking to enhance their understanding of resistor configurations and circuit simplification techniques.

Homework Statement



What single, equivalent resistor could replace all of the resistors in this circuit?HELP: If you study the diagram, you will see one pair of resistors which is in parallel. Replace this pair with a single equivalent resistor and re-draw the circuit.

HELP: If you have followed the previous suggestion, you will now see a pair of resistors which is in series. Replace this pair with a single equivalent resistor and re-draw the circuit again.

here is an image of the circuit: https://tycho-s.physics.wisc.edu/cgi/courses/shell/common/showme.pl?courses/phys104/fall09/homework/04/r2/ex1s95p3.gif
R1=2 R2=5 R3=13 R4=8

Homework Equations



Req parallel: 1/R1 + 1/R2 = 1/Req

Req series: R1 + R2 =Req

The Attempt at a Solution



I've tried to redraw the circuit where Req= R1 + R2 + [1/(1/R3)+(1/R4)] but that didn't work, any suggestions to which two resistors in the image are parallel to one another to get me started on redrawing the circuit, just to simplify the circuit?

Thanks
