For combination 1 :
two resistors are in parallel and their parallel combination is given as
Rp = (R R)/(R + R) = R/2
Combination of parallel resistors are in turn in series with each other and their series combination is given as
Req = Rp + Rp
Req = R/2 + R/2
Req = R
For combination 2 :
two resistors are in parallel and their parallel combination is given as
1/Rp = 1/R + 1/R + 1/R
Rp = R/3
parallel combination Rp and R are in series and their series combination is given as
Req = Rp + R
Req = R/3 + R
Req = 1.33 R
So combination 1 has lower resistance
