Draw the circuit diagram for 3 cells connected in series, two resistors in series and a switch. If V = I x R, calculate l if one cell = 2V and the resistor = 4Ω.​

Air is compressed isentropically from an initial state of 300 k and 101 kpa to a final temperature of 1000 k. determine the final pressure using the following approaches: (a) approximate analysis (using properties at the average temperature) (b) exact analysis
