B&S (Americаn stаndаrd) 14-gauge annealed cоpper wire is cоmmоnly used in household wiring. Its diameter is 0.1628 cm. (Note: The resistivity of annealed copper is 1.72 x 10-8 Ω · m . The temperature coefficient of resistivity of annealed copper is 3.9 x 10-3 K-1.) (a) Find the resistance of a 12.0 cm length of this wire at room temperature? R = [BLANK-1] Ω (b) This household wire is rated to carry a maximum current of 15.0 A. When it is carrying this current, what is the potential difference (i.e. voltage) across the ends of the wire? V = [BLANK-2] V (c) What is the resistance of the annealed copper wire at -5.000C? R = [BLANK-3] Ω
