Question

If the measured value of resistance R= 1.05 ohm wire diameter d=0.60mm, length l=75.3 cm then find the maximum permissible error in resistivity rho=R(pid square /4) upon me l​

Answer 1

Explanation:

If the measured value of resistance R=1.05Ω wire diameter d=0.60mm, and length l=75.3cm, then find the maximum permissible error in resistivity, ρ=l

R(πd

2/4)
