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.

The resistance of a wire is given by R = R.[1+ a(T – T.)] where T.
= 20 °C, R, = 6 N ± 0.3 % is the resistance at 20 °C, a = 0.004/ °C
±1 % is the temperature coefficient of resistance, and the temperature
of the wire is T = 30+1 °C. Determine (a) the normal resistance of the
wire and (b) the uncertainty in the resistance of the wire, ur
