When the cold junction of a thermocouple is maintained at `0^(@)C`, the thermo em .e., generated by this thermocouple is given by the relation
`e=[16*8+(1)/(2)(-0*0480) theta^(2)]xx10^(-6)`
where `theta` is the temperature of the hot junction in `""^(@)C`. Find the neutral temperature of this thermocouple.
