Answer:
The temperature coefficient of resistance is 0.13333 °C⁻¹
Explanation:
In the context to the given question we have to find the temperature coefficient of resistance
given,
T₁ = 25⁰C.
T₂ = 100⁰C.
R₁ = 1 Ω
R₂ = 2Ω
We know that;
temperature coefficient =( R₂ -R₁) / R₁ (T₂ -T₁)
= ( 2-1 )/ 1(100-25)
= 1 / 75 °C⁻¹
=0.13333 °C⁻¹
The temperature coefficient of resistance is 0.13333 °C⁻¹
