Metal 1 POTENTIOMETER V(mV) Metal 2 A voltage generated at the metal junction is read on a potentiometer or millivoltmeter. When certain metals are used, the voltage varies expon with the temperature at the junction of the two metals: V(mV) = a exp(b.T ('C)) An iron-constantan thermocouple (constantan is an alloy of copper and nickel) is calibrated by inserting its junction in boiling water and measuring a voltage 6 mV, and then inserting the junction in gold at its melting point and measuring 72 mV. 1. Using linearization method find the value of the constant a and b. 2. Derive and equation for V measured in V in terms of T measured in (°R).
