An advanced lab student is studying the effect of temperature on the resistance of a current carrying wire. She applies a voltage to a tungsten wire at a temperature of 52.0∘C and notes that it produces a current of 1.20 A. If she then applies the same voltage to the same wire at −88.0∘C, what current should she expect (in A)? The temperature coefficient of resistivity for tungsten is 4.50×10−3(∘C)−1. (Assume that the reference temperature is 20∘C.) A

A Geiger counter detects radiation such as alpha particles by using the fact that the radiation ionizes the air along its path. A thin wire lies on the axis of a hollow metal cylinder and is insulated from it (Figure 1). A large potential difference is established between the wire and the outer cylinder, with the wire at higher potential; this sets up a strong electric field directed radially outward. When ionizing radiation enters the device, it ionizes a few air molecules. The free electrons produced are accelerated by the electric field toward the wire and, on the way there, ionize many more air molecules. Thus a current pulse is produced that can be detected by appropriate electronic circuitry and converted to an audible "click." Suppose the radius of the central wire is 145 μm and the radius of the hollow cylinder is 1.80 cm. Part A What potential difference between the wire and the cylinder produces an electric field of 2.00×104 V/m at a distance of 1.20 cm from the axis of the wire? (Assume that the wire and cylinder are both very long in comparison to their radii.) Submit Request Answer Figure 1 of 1

You just landed a job as an assistant to an electrician who is working on a building site. He is making use of long single-conductor insulated wire for some of the connections in the complicated "smart building." A new shipment of spools of this wire has been delivered, and the electrician is not happy that it came from a manufacturer that he suspects is producing inferior wire. The electrician asks you to determine the resistance per unit length of the wire (in Ω/m ) and provides you with a battery and a high-quality multimeter. Despite the quality of the meter, he suggests that you not use the ohmmeter to measure resistance, because the value of the resistance is so low that the meter is not likely to measure it accurately. You are puzzled as to how to go about this task. As the electrician runs off to attend to another task, he says, "Cut off a couple of different lengths of wire and use the battery and the multimeter. " You put the multimeter in voltage mode across the terminals of the battery without a wire connected and measure 7.00 V. You then cut off two lengths of wire, one 5.00 m in length, and one 10.0 m in length. Connecting them one at a time to the battery through the multimeter in current mode, you find that there is a current of 5.17 A in the 5.00 m length of wire, and 3.00 A in the 10.0 m length of wire. Ah-ha, now you have enough information! Ω/m
