Physics - Current Electricity Question with Solution | TestHub

In an experiment, current measured is, $I=10.0$ A, potential difference measured is $V=100.0$ V, length of the wire is 31.4 cm and the diameter of the wire is 2.00 mm (all in correct significant figures). Find resistivity of the wire in correct significant figures. [Take $\pi =3.14$, exact] Take the resistivity as $\rho =P\times 10^{-4}\Omega$-m and find $P$.
