➧ Resistance of a PIECE of wire is PROPORTIONAL to its length. A piece of wire has a resistance R. The wire is CUT into five equal parts.

➧ Therefore, resistance of each part
➾ R/5

➧ All the five parts are connected in parallel.

∴equivalent resistance (R') is given as

1 / R'
➾ 5 / R + 5 / R + 5 / R + 5 / R + 5

➾ 5 + 5 + 5 + 5 + 5 / R

➾ 1 / R' = 25 / R

➾ R / R' = 25 ...✔
