Homework Help Overview

The discussion revolves around solving for unknown values in a complex circuit involving resistors in parallel. Participants are tasked with finding unknown resistances (R), currents (I), and voltages (V) based on given equations and relationships.

Discussion Character

  • Exploratory, Conceptual clarification, Assumption checking

Approaches and Questions Raised

  • The original poster identifies the unknowns in the circuit and expresses a need for additional information to proceed. Some participants question the equality of voltages across parallel resistors and seek clarification on this concept.

Discussion Status

Participants are actively engaging with the concepts of voltage in parallel circuits, with some confirming their understanding of the relationships between the voltages. There is an acknowledgment of the need for further information to solve the problem completely.

Contextual Notes

There is a mention of a potential lack of information needed to solve for all unknowns, which may affect the progress of the discussion.

Find all the unkown R,I's, V's


Homework Equations


Reg=(R1*R2*R3)/(R1+R2+R3)
it=i1+i2+i3
V=IR

The Attempt at a Solution



All unknowns:
R2,R3,i1,i3 it,Vs,V1,V2

It seems that I need one more bit of information to solve any variables
i1 goes across R1, i2 goes across R2, i3 across R3

Hint: Since the three resistors are in parallel, what's the voltage across each? (And the battery voltage, for that matter.)
 
Since they are parrallel the voltage across each is equal to each other? Vs=V1=V2=V3 is this right?!? Also why is that?
 
Ok thank you knowing this concept this should be an easy one...I have another simple question though.I will post the picture and work in a new thread that I will pm you, can you just come teach my class for me? Your anwsers are so much more simplier then the ones provided by my professor.
