At room temperature (27^ C ) , the resistance of a heating element is 50 . The temperature coefficient of the material is 2.4 10⁻⁴ ^ C ⁻¹ . The temperature of the element, when its resistance is 62 , is _____ ^ C .
Correct answer
0
Step-by-step solution
aligned & R = R ₀(1+ T ) & 62=50 [1+2.4 10⁻⁴ T ] & T =1000^ C & T -27^ =1000^ C & T =1027^ C aligned
