Question

$\mathrm{R}=\frac{\rho \mathrm{L}}{\pi \frac{\mathrm{d}^2}{4}}$

$\frac{\Delta \mathrm{R}}{\mathrm{R}}=\frac{\Delta \mathrm{L}}{\mathrm{L}}+\frac{2

Vedclass · Accepted Answer

$0.3 \%$

Vedclass · Answer

$\mathrm{R}=\frac{ho \mathrm{L}}{\pi \frac{\mathrm{d}^2}{4}}$

$\frac{\Delta \mathrm{R}}{\mathrm{R}}=\frac{\Delta \mathrm{L}}{\mathrm{L}}+\frac{2 \Delta \mathrm{d}}{\mathrm{d}}$

$\frac{\Delta \mathrm{L}}{\mathrm{L}}=0.1 \% 	ext { and } \frac{\Delta \mathrm{d}}{\mathrm{d}}=0.1 \%$

$\frac{\Delta \mathrm{R}}{\mathrm{R}}=0.3 \%$
