What is the resistance of a nichrome wire at 0.0 ∘c if its resistance is 200.00 ω at 11.5 ∘c?

The temperature of the resistor varies based on the variation in the temperature. The equation that describes the relation between the two of them is:
R = R0[1+ alpha(T-T0)]  where:
R is the new resistance we are looking for
alpha is the temperature coefficient of resistance. For nichrome, alpha = 4x10^-4/C
T0 is the standard temperature =11.5
R0 is the resistance at T0 = 200 ohms
T is the temperature at which we want to get R = 0

Substitute in the equation to get R as follows:
R = 200 [1+4*10^-4 (0-11.5)] = 199.08 ohm
