Determine the length (in mm) of a gold conductor that has a resistance of 0.019 Ω and a cross-sectional area of 2.1 x 10-9 m2. The resistivity of gold is 2.2 x 10-8 Ω-m [round your final answer to one decimal place]. An aluminum conductor with the same length and area as in Question above would have a higher resistance than the gold conductor. The resistivity of aluminum is 2.6 x 10-8 Ω-m. True or false

A 62.4 cm length of the material has a circular cross-section of diameter 12.1 mm. When a potential difference of 87 V is placed across the length of the material, a current of 12.5 mA flows. Calculate the resistivity of the wire. Give your answer to 2 decimal places.
2. Page > of 3 5. Two long coaxial metal cylinders with radii a and b are separated by material of conductivity o (see figure below). The conductivity is not uniform and changes as = (s)0 where k is a constant. If the two cylinders are kept at a potential difference V, find the resistance R between the cylinders. (s)o Hint: Since the conductivity is a function of position, the charge density in the resistive medium is not zero and E does not go like 1/s. However, since the current I is steady, the same current flows across each eylindrical surface. Instead of using Gauss' Law, find E in terms of I, from Ohm's Law. acer F10 F11
