The question is a thermodynamics question where the system is a resistor in a circuit; the question is as follows:

A thermally insulated (Adiabatic) resistor of30 Ohm'shas a current of2 Amperespassed through it for1 second. It is initially at20 degrees celcius(= 293 degrees K). The mass,mof the resistor is6 grams. IfCp(specific heat capacity at constant pressure)= 850 J/kg-Kcalculate :

a). The temperature increase, and

b). The change in entropy (Sf - Si) of the resistor and the universe.

(Hint: The actual process is dissipative. Imagine a reversible process taking it between the 2 equilibrium states.)
