Q$1-$ A resistive$-$type temperature sensor has the following specifications:

$654[]$ resistance $atT=117K$

$375[]$ resistance $atT=303K$

Hence, determine the resistance value for the sensor at temperature $T=200K$ if the sensor has:

a$)$ A linear temperature relationship of the form $R=a_{1}T+b_1$

b$)$ An exponential temperature relationship of the form $R=a_2$exp$(\frac{b_2}{T})$

Where $a_1,b_1,a_2$ and $b_2$ are constants?

Don't forget to include the correct units in your answers!!!
