16. 17. 18. At what temperature will aluminium have the same resistivity that tungsten has at 2.0 x 101 \"C. Some data: pm = 2.55 x 108 (at 20C) pw = 5.0 x 10-8 (at 20C) 05A] = 0.00429 aw = 0.0045 (0) 280C (b) 110C (0) -97C (d) 490C (:4) 560C A length of aluminium wire is connected to a precision 10.00V power supply, and a current of 0.4212 A is precisely measured at 235C. The wire is placed in a new environment of unknown temperature where the measured current is 0.3818 A. What is the unknown temperature? (a) 497C 03) 479C (c) 794C (0) -94.7C (e) 914C In the following circuit what is the current produced by the voltage supply '03? v1=e.0v 1:11:1er (a) 0.3 A (b) 0.9 A (c) 1.0 A (911.114 (e) 1.24
