The specific resistance `rho` of a circular wire of radius `r`, resistance `R`, and length `l` is given by `rho = pi r^(2) R//l`. Given : ` r = 0.24 +- 0.02 cm , R = 30 +- 1 Omega` , and `l = 4.80 +- 0.01 cm`. The percentage error in `rho` is nearly

The specific resistance rho of a thin wire of radius r cm, resistance R ohm and length L is given by rho = (pi r^2R)/(L). If L =78+-0.01cm r = 0.26 +- 0.02 and R =32 +- 1 Omega, What is the percentage error in rho?

The specific resistance of a circular cross - section of a cylindrical wire of radius b and resistance R is given is s=(pi b^(2)R)/(l) , where l is it's length. If b=(24+0.02)cm , R=(130+1)Omega , l = (4.0+0.01)cm , the percentage error in s is nearly.

The radius (r) , length (l) and resistance (x) of a thin wire are (0.2 +- 0.02)cm, (80 +- 0.1)cm , and (30 +- 1) Omega respectively. The percentage error in the specific resistance is

The resistance between ends will be (if (rho L)/(pi R^2) = R_0) .
