thermocouple is embedded on a surface during an experiment and it records a steady temperature value of $50$ deg $*$ C when the source temperature is $60$ deg $*$ C and the ambient temperature is $30$ degree C$.$ What will be the temperature recorded by the thermocouple when the source temperature changes to $90$ deg $*$ C the same ambient temperature What will be the dynamic temperature recorded by the thermocouple, if the source temperature varies as $(190+20$ sin $5$t$)$ C$,$ and the time constant of the thermocouple is $0\mathrm{.}1$
