To find the temperature of inversion for the thermocouple given the thermo emf equation \( E = 40T - \frac{T^2}{20} \), we will follow these steps: ### Step 1: Understand the given equation The thermo emf \( E \) varies with temperature \( T \) of the junction, where the cold junction is at \( 0^\circ C \). The equation is: \[ E = 40T - \frac{T^2}{20} \] ...
