Explanation:
Hi
I will answer this
Resistance equivalent in parallel is given by R1 *R2 / (R1+R2)
Resistance equivalent in series is R1 + R2
Given R1 + R2 = 16
and R eq in parallel as 3
sustitute the above values in the first equation of parallel equivalence
we get R1*R2 = 3*16 = 48
The values of R1 and R2 are 12,4
By using basic calculations of (R1-R2)^2 = (R1 +R2)^2 - 4R1R2
R1 - R2 = sqrt(256-192) = sqrt(64) = 8
solving R1 and R2 we get r1 =12 and r2 =4
