To determine the resistance of a wire at a given temperature, we need to know the material's temperature coefficient of resistance (α) and the resistance at a reference temperature (R₀).
The temperature coefficient of resistance measures how much the resistance of a material changes with temperature. It is typically given in units of ohms per degree Celsius (Ω/°C) or ohms per degree Kelvin (Ω/K).
The formula to calculate the resistance of a wire at a given temperature is:
R = R₀ * (1 + α * (T - T₀))
where:
R is the resistance at the given temperature T,
R₀ is the resistance at the reference temperature T₀,
α is the temperature coefficient of resistance,
and T is the given temperature.
In this case, we are given the resistance of the wire at 300K (T = 300K) as 0.3 ohms. However, we do not have the reference temperature or the temperature coefficient of resistance.
Without this information, we cannot accurately calculate the resistance of the wire at any other temperature.
