Question

how would you join three identical resistors Of resistance R, so that the equivalent resistance Of the combination is (1)2R/3 , (2)3R/2

Answer 1

1)
Join the first two on series
Rs=R+R
Rs=2R
Join the third resistance in parallel
1/Rp=1/2R+1/R
1/Rp=3/2R
Rp=2R/3

2)
Join the first two resistance in parallel
1/Rp=1/R+1/R
1/Rp=2/R
Rp=R/2
Join the third resistance in series
Rs=2/R+R
Rs=3R/2
