Tivo resistors are hooked up in parallel: 5 ohms and 10 ohms. Compare the voltage across and the current through the resistors. The 5 ohm resistor has the same current and half the voltage as the 10 ohm resistor
The 10 ohm resistor has the same current and half the voltage as the 5 ohm resistor
The 5 ohm resistor has the same voltage and half the current as the 10 ohm resistor
The 10 ohm resistor has the same voltage and half the current as the 5 ohm resistor

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.
