Compute the electrical conductivity ((ωm)−1 ) of a cylindrical silicon specimen 5.1 mm in diameter and 51 mm in length in which a current of 0.1 a passes in an axial direction. a voltage of 12.5 v is measured across two probes that are separated by 38 mm.

Answerthe energy required is 1.60 × 10⁻¹⁸ j, to three significant figures.explanationwe define electric potential as the ratio electric potential energy to the charge,    then the following gives us the potential difference,      the formula  may be on your formula sheet.the change in electric potential energy would be the energy that would needed to move it from point a to point b. solving for that, we get    using q = 8.00  × 10⁻¹⁹ c and  δv = 2.00 v, we get    the energy required is 1.60 × 10⁻¹⁸ j, to three significant figures.
