What is the equivalent resistance of the combination
Since R is directly proportional to length of the wire.
when wire is cut into n equal parts, then Resistance of each parts, then
Resistance of each part=R/n
When the n wires are connected in parallel, then the equivalent resistance of combination is
1/R 2(subscript)=n/R ÷ n/R ÷ n/R …………. n times
1/R 2(subscript) = n square/R
R 2(subscript) = R/n square
