Choose true or false for each statement regarding the resistance of a wire. While maintaining a constant voltage V, the current I increases when the resistivity p of a wire decreases. OWhile maintaining a constant voltage V, the current I increases when the cross-sectional area A of a wire expands. The resistance is inversely proportional to the cross-sectional area A of the wire. Submit Answer Tries 0/3 Choose true or false for each statement regarding resistors in a circuit. If you connect two different resistors in series in a circuit, then the current that flows through each of them is the same. 8 If you connect two different resistors in parallel in a circuit, then the voltage across each of them is the same. 8 Two identical resistors in parallel have half the resistance of each individual one.

A certain metal has a temperature coefficient of resistivity of 0.0064 (°C) -1. A wire made from that material is connected to a source of constant voltage via a switch. At the instant the switch is closed, the temperature of the wire is 27 °C, and the initial power dissipated in the wire is Po. At what wire temperature has the power dissipated in the wire decreased to (1/2)Po? Number Units

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
