Question # The resistance of a resistance thermomerer has value ( 2.71 Omega ) and ( 3.70 Omega ) at ( 10^{circ} mathrm{C} ) and 100 el pespectively. The temperature at which the resistance is ( 3.26 Omega ) is:

# The resistance of a resistance thermomerer has value ( 2.71 Omega ) and ( 3.70 Omega ) at ( 10^{circ} mathrm{C} ) and 100 el pespectively. The temperature at which the resistance is ( 3.26 Omega ) is:

a) ( 40^{circ} mathrm{C} )

b) ( 50^{circ} 6 )

( 5160^{circ} mathrm{C} )

d) ( 70 % )

Solution

According to the question, change in resistance ( =370-2.7 i=0.99 Omega ) and corresponding change in temperature =100-10=90C [ begin{array}{c}text { so change in resistance (new) }=3.26-2.71=0.55 Omega text { Herre the corresponding change in temperature } text { would be }=frac{90}{0.99} times 0.55=50^{circ} mathrm{c}end{array} ]
