The expression ...Here is the answer for Tech solve:<br />The expression for thermo emf āEā in the present case is<br /> E = b(T - 273) + c(T - 273)2 where T is the temperature of hot junction in Kelvin.<br />At neutral temperature dE/dT = 0<br />Therefore, b + 2c(Tn - 273) = 0 where Tn is the neutral temperature in Kelvin.<br />This gives (Tn - 273) = - b/2c<br />The neutral temperature tn in degree Celsius = - b/2c<br />Peltier coefficient Ļ = T dE/dT = T[b + 2c(T - 273)] = T(b + 2ct) where t is the temperature of hot junction in degree Celsius.<br />Thomson coefficient Ļ = T (d2E/dT2) = 2cT<br />MVhttps://www.blogger.com/profile/05910408858112321196noreply@blogger.comtag:blogger.com,1999:blog-32436271.post-87881354116625295482017-08-25T07:57:45.362+05:302017-08-25T07:57:45.362+05:30the EMF of a Thermocouple, one junction of which i...the EMF of a Thermocouple, one junction of which is kept at zero degree celsius is given by E= bt+ Ct2.
