Question

A thermistors resistance varies with temperature as: R=R0eBT where R is in ohms Ω, T is in kelvins, and R0 and B are constants. If R=6900 Ω at the ice point and R=250 Ω at the steam point, Ts=373.15K. What is the rate of change of the resistance with temperature dRdT symbolically?

Hint: dRdT=?

Enter 1 for A), 2 for B), 3 for C), 4 for D), 5 for E) A) dRdT=ddT(R0eBT)=-RBT⋅eBT B) dRdT=ddT(R0eBT))=-RBT2⋅eBT C) dRdT=ddT(R0eBT)=-RBT3⋅eBT D) dRdT=ddT(R0eBT))=-(R⋅B⋅T) E) dRdT=ddT(R0eBT)=-R⋅B⋅T
