5) A 400,000 CM cable is composed of 37 strands. What is the diameter, in mils, of each strands? 6) Each of the 19 strands of a copper cable has a diameter of 59 mils. Calculate the resistance of a foot of such cable at a temperature of 20°C. 7) What kind of material is used in construction of a 39 22 rheostat (a variable resistance) if the wire has a length of 266 ft. and a diameter of 22.6 mils? (look for a table containing resistivity of materials).
