Your math is wrong (should be ~15.7K). Two resistors in parallel are Req=(R1*R2)/(R1+R2) Three or more are Req=1/( (1/R1) + (1/R2) + ... + (1/Rn) )

Only if they are both rhe same value.

I can understand doing 'sleep deprivation math' (college had me doing plenty )....I was not trying to criticize; Just trying to help with the correct formula(s).
