An RTD (resistance temperature detector) element is made from $$50\mathrm{cm}$$ of $$0.01\mathrm{mm}$$ diameter nickel wire. For the following questions, use the resistivity, and temperature coefficient of resistivity, found in Table $$12.1$$ in your textbook. (The small difference is due to a different nominal temperature for Table 12.1, probably $$25^{?}\mathrm{C}$$.) (a) What is the nominal resistance of this element? (b) If the temperature coefficient of resistivity is assumed to be constant, by how much will the RTD resistance change per $${}^{?}\mathrm{C}$$ ? Per $${}^{?}\mathrm{F}?R(T)=R_0\left[1+A\left(T?T_0\right)\right]$$ TABLE 1: Representative Properties of Various Grid Materials
