8.6. A current of 10 A is maintained for 1s in a resistor of 25 N while the temperature ofthe resistor is kept constant at 27°C.(a) What is the entropy change of the resistor?(b) What is the entropy change of the universe?The same current is maintained for the same time in the same resistor, but nowthermally insulated, with the same initial temperature. If the resistor has a mass of10g and a specific heat of 836 J/kg - K:(c) What is the entropy change of the resistor?(d) What is the entropy change of the universe?

Since we only answer up to 3 sub-parts, we’ll answer the first 3. Please resubmit the question and…
