The table below shows the variation of electrical resistance of a 1000-m length of copper wire with a range of wire gauage numbers. Using extrapolation, estimate the resistance of a 1000-m length of copper wire for a wire gauge number of 34. Identifiy the variable needed. Wire gauge number Resistance (0) 20 33.31 22 52.96 24 84.21 26 133.9 28 212.9 30 338.6 Answer: Hint: enter the correct variable (example: z) before the = sign and the correct number after the = sign
