In the experiment of Ohm's law, when potential difference of 10.0 V is applied, current measured is 1.00 A. If length of wire is found to be 10.0cm and diameter of wire 2.50 mm, then find maximum permissible percentage error in resistivity.

A

`1.8%`

B

`10.2%`

C

`3.8%`

D

`5.75%`

Text Solution

Verified by Experts

`((Deltarho)/(rho))_(max)=2((0.01)/(2.50))+((0.1)/(10.0))+((0.1)/(10.0))+((0.01)/(1.00))=3.8%` .
