In series, resultant resistance = 3r
In parallel, resultant resistance = r/3
ratio = series/parallel
= 3r/(r/3) = 9
ratio = 9:1
In parallel, resultant resistance = r/3
ratio = series/parallel
= 3r/(r/3) = 9
ratio = 9:1

Answer:
The ratio is 9:1
Explanation:
let, the resistance be r
when three r resistance are in series
the equivalent resistance = r + r + r = 3r
when three r resistance are in parallel
1/the equivalent resistance = 1/r +1/r+1/r
the equivalent resistance = r/3
now, ratio = series/ parallel
ratio = 3r*3/r
ratio = 9/1
so, ratio is 9:1
