A tungsten wire has a radius of 0.075 mm . The coefficient of resistivity is 5.6...
A tungsten wire has a radius of 0.097 mm and is heated from 20.0 to 1418 oC. The temperature coefficient of resistivity is α = 4.5 x 10-3 (Co)-1. When 120 V is applied across the ends of the hot wire, a current of 2.4 A is produced. How long is the wire? Neglect any effects due to thermal expansion of the wire.
A tungsten wire has a radius of 0.076 mm and is heated from 20.0 to 1305 °C. The temperature coefficient of resistivity is α = 4.5 10-3 (C°)−1. When 120 V is applied across the ends of the hot wire, a current of 1.9 A is produced. How long is the wire? Neglect any effects due to thermal expansion of the wire.
A tungsten wire has a radius of 0.087 mm and is heated from 20.0 to 1334 oC. The temperature coefficient of resistivity is α = 4.5 x 10-3 (Co)-1. When 150 V is applied across the ends of the hot wire, a current of 1.3 A is produced. How long is the wire? Neglect any effects due to thermal expansion of the wire. help!!
