Question
The resistance of a wire is given by R = Ro[1 + (T ? To)] where To
= 20 C, Ro = 6
0:3 % is the resistance at 20 C, = 0:004/ C
1 % is the temperature coecient of resistance, and the temperature
of the wire is T = 301 C. Determine (a) the normal resistance of the
wire and (b) the uncertainty in the resistance of the wire, uR.
