There is no unique solution. There must be some other condition. For example R1 + R2 must be 20K Ohms. Now there is a unique solution because you have two equations and two unknowns.Originally posted by Steve1992@May 7 2006, 08:33 AM
Vout = Vin x R2 / (R1 + R2)
If Vin is 12V and I want Vout to be 4.5V
What would the equation/math be to find the values for R2 and/or R1 if given.
If R1 is given R2 would be a common factor?
