This is hopelessly fragmented. I can't tell which resistors are in which configurations.Given total resistance in a combination circuit find the missing value of R2
Rt= 23,250ohms
in series R1= 12,000ohms
in parallel with R2 is R3 which equals 18,000 ohms
R2 =?
Not speaking good English is just fine - we can work through that. But just working the problem for someone without them having to lift a finger is highly frowned on (not to mention against the AAC guidelines for the Homework Help forum).The problem here I think is the OP doesn't speek goodly inglish!
My guess is R2=30KΩ
Guess:
R2 and R3 are in parallel. This set is in series with R1. Total = 23250Ω
R(total) = R1 + 1/(1/R2 + 1/R3)
so
R2= 1/[1/(Rtotal-R1)-1/R3]
(where Rtotal = 23250, R1=12000, R3=18000)
so
R2 = 1/[1/(23250-12000) - 1/18000] = 30K
QED. If it right???!

Oops, sorry I didn't realize about the rules (and the goodly inglish was only a joke). I'll be more careful next time to let the OP show they've done a bit of homework first.Not speaking good English is just fine - we can work through that.
