Tutorial 12 #1. A toaster contains a heating element that has a resistance of 1402. This heating element is energized by a 120 V outlet. What is the current in the heating element? #2. A round wire of length 2.80 m has a radius of 1.03 mm. It carries a current of 1.35 A, when a voltage of 0.0301 V is applied across the ends of the wire. Referring to Table 11.1 (p.290) (https://cnx.org/contents/2PdNED-z@13.1:pelFiTvw@7/Resistance-and- Resistivity#import-auto-id1375921), deduce what material the wire is made of. #3. An MP3 player operates with a voltage of 3.7 V, and is using 0.093 W of power. Find the current being supplied by the battery.
