(i) Series combination: 

begin mathsize 12px style 1 over straight K equals 1 over straight k plus 1 over straight k equals 2 over straight k therefore straight K equals straight k over 2 end style

(ii) Parallel combination:

begin mathsize 12px style straight K equals straight k plus straight k equals 2 straight k end style
