What single, equivalent resistor could replace all of the resistors in this circuit? Rtot = Ω 2 NO 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 [Broken] Req parallel: 1/R1 + 1/R2 = 1/Req Req series: R1 + R2 =Req R1=2 R2=5 R3=13 R4=8 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 to solve the problem?
