In the problem i have to find the values of resistors using voltage divider, and use KVL to determine the currents.
Vi= [Ri / (R1+R2+...+Rn)] * Vs
1/Rtotal = 1/R1 + 1/R2 + ... + 1/Rn
Ʃrise + Ʃdrop = 0
The Attempt at a Solution
In order for us to use voltage divider the resistors must be in series.
Req = (40*R2)/(40+R2), but we still don't know the resistance of R2.
However, later I tried to use the KVL equation to find the voltage for Req.
-24+8+Veq = 0 → Veq = 16 V
Then I used the voltage divider equation:
Veq = [Req / (R1 + Req) ]* Vs // but again we have two unknowns here again
And that's the point where I stuck, I know this problem is trivial but my brain cannot come up with anything else to solve this.
