Answer the following problems in a short/long bond paper size. Round off your answer up to 2 decimals, if applicable. Show your complete solution and box your final answer. You may not copy the problem. 1. A cable has 19 strands of copper conductors having a diameter of 0.06 in each. Find the resistance of mile length of such cable. 2. A semi-circular ring of copper has an inner radius of 6 cm, outer radius of 9 cm and an axial thickness 4 cm. Find the resistance of the ring between its two end faces. 3. A given conductor has a resistance of 0.5 12. It is drawn down to reduce its diameter to one-fourth of its original diameter. Find its new resistance. 4. A copper conductor has a resistance of 50 at 30°C. Find its resistance at 90°C. 5. A conductor has a resistance of 7 N at 0°С. Find the temperature coefficient of the conductor at 20°C if its resistance increases to 7.8 at 20°C.
