You apply a potential difference of 4.3 V between the ends of a wire that is 2.2 m in length and 0.662 mm in radius. The resulting current through the wire is 17.6 A. What is the resistivity of the wire? (Give your answer in scientific notation using Ohm.m (Ω.m) as unit)
A 7.5 V potential difference is applied between the ends of a 0.70-mm-diameter, 50-cm-longnichrome wire. What is the current in the wire? Express your answer using two significant figures.

A potential difference of 100 V is maintained across the two ends of a nickel wire of radius 2 mm and length 10 m. Calculate (a) the electric field intensity, (b) the current density, and (c) the electric current through the wire
A 8.0 V potential difference is applied between the ends of a 0.80-mm-diameter, 90-cm-long nichrome wire. What is the current in the wire?
A typical overhead power line is bare wire at a high potential relative to ground. A local line receives power at 3300 V with respect to the ground; the delivered voltage is slightly less, due to resistance loss in the wire. The wire is 10 km long, carries a current of 60 A, and has a resistance (made small to limit power loss) of 2.5 Ω. 1) Approximately how much power is lost due to the resistance of the wire?...
In one of NASA's space tether experiments, a 20.0 km-long conducting wire was deployed by the space shuttle as it orbited at 7.86 x 103 m/s around Earth and across Earth's magnetic field lines. The resulting motional emf was used as a power source. If the component of Earth's magnetic field perpendicular to the tether was 1.65 x 10T, determine the maximum possible potential difference (in V) between the two ends of the tether. HINT
A 5.0 V potential difference is applied between the ends of a 0.80-mm-diameter, 85-cm-long nichrome wire. What is the current in the wire? resistivity of nichrome is 1.5*10^-6 (I think, if im wrong use something else)
