Project Summary: 3 short questions Electrical engineering If a copper conductor has a resistance of 15Ω at 0°C, what will it's resistance be when temperature is increased to 25°C and α0=0.00427? Answer should be to 2 d.p. - You do not need to enter a unit with your answer. Calculate the resistance of a material with a length of 6.0m and cross-sectional area of 9.58mm2. (The resistivity of the material is 1.68x10-8 Ω.m) Give your answer to 4 d.p. Calculate the resistance of a material with a length of 9.7m and cross-sectional area of 6.70mm2. (The resistivity of the material is 1.68x10-8 Ω.m) Give your answer to 4 d.p.
