There is a potential difference of 1.9 V between the ends of a 20 cm long graphite rod that has a cross-sectional area of 1.3 mm^2. The resistivity of graphite is 7.5 x 10^-6 ohm-m. Find the resistance of the rod. Find the current. Find the electric field inside the rod.
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)
The electric field inside a 30-cm-long copper wire is 0.010 V/m. What is the potential difference between the ends of the wire?
Hellllpppp A wire Is 1.1 m long and 1.1 mm^2 in cross-sectional area. It carries a current of 5.6 A when a 2.1 V potential difference Is applied between its ends. Calculate the conductivity o of the material of which this wire Is made.
A resistor is constructed of a carbon rod that has a uniform cross-sectional area of 4.90 mm2. when a potential difference of 20.0 V is applied across the ends of the rod, the rod carries a current of 3.60 x 103 A (a) Find the resistance of the rod kS2 (b) Find the rod's length.

A wire is 1.3 m long and 0.93 mm2 in cross-sectional area. It carries a current of 5.8 A when a 1.8 V potential difference is applied between its ends. Calculate the conductivity σ of the material of which this wire is made.
The electric eel (Electrophorus electricus) can generate a potential difference of 600 V between a region just behind its head and its tail. Suppose an unsuspecting fish swims into this area, resulting in a lethal current of 1.1 A passing through the length of its body. If the fish is approximately 31 cm in length and 7.5 cm in diameter, what is its average resistivity?
