3. ohm’s law is represented by the equation i=v/r. explain how the current would change if the amount of resistance decreased and the voltage stayed the same. (hint: try plugging numbers into the equation for r, but make sure v stays the same. then describe what happens to i(current)

Air enters a gas turbine with two stages of compression and two stages of expansion at 100 kpa and 17°c. this system uses a regenerator as well as reheating and intercooling – the intercooler returns the air to the inlet temperature. the pressure ratio across each compressor is 4 ; 300 kj/kg of heat are added to the air in each combustion chamber; and the regenerator operates perfectly while increasing the temperature of the cold air by 20°c. determine the system’s thermal efficiency. assume isentropic operations for all compressor and the turbine stages and use constant specific heats at room temperature.
