0.6. The resistance of a certain size of copper wire is given as: R = Ro[1+ a(T-20)] where Ro-62±0.3 percent is the resistance at 20°C, a=0.004°C-+1 percent is the temperature coefficient of resistance, and the temperature of the wire is T=30°C ±1 percent. Calculate the resistance of wire and its uncertainty.
