In 1878 British scientist Swan invented the modern light bulb. ) True D False -. Silver is a conductor. ) True O False . Very fine wire may be insulated by glass fibers. True FalseA transmission line cable consists of 19 strands of identical copper conductors, each 1.5 mm in diameter. The length of the cable is 2 km but because of the twist of the strands, the actual length of each conductor is increased by 5 percent. What is resistance of the cable ? Take the resistivity of the copper to be 1.78 ×10^–8 m.
