Derive the length of the conductor (l) from the resistance formula: R = (p * l) / S 30 ptc.

To make it easier to express the length of the conductor from this formula, I propose to make a conversion to proportion. The formula is written as follows: R = (p * l) / S, but we write it in proportion, that is, so that the product of the extreme is equal to the product of the averages. We get: RS = PL. From here it is not difficult to express l: l = RS / P.
