How many times will the resistance of the conductor increase / decrease when the length is halved.
| July 3, 2021 | education
To estimate the desired change in the resistance of a given conductor, we will use the ratio: Rc / Rn = k = (ρ * lc / S) / (ρ * ln / S) = lc / ln.
Variable ratio: lk (final length of a given conductor) = 1/2 ln (initial length).
Calculation: k = lc / ln = 1/2 ln / ln = 1/2.
Answer: The resistance of a given conductor will decrease by 2 times.
