For the diode circuit shown in Figure C1, assume the Turn-On voltage of LED is 2.0V and LED is 1.4V. Calculate current I, that flows through Resistor Rz
i
If the switch S1 is closed and S2 is open
i. If the switch S2 is closed and S1 is open
in. If both the switches are closed

An engine runs on the ideal diesel cycle. the cycle has a compression ratio of 20 and a cutoff ratio of 2. the highest temperature in the cycle is 1200 k. if the heat into the system is 300 kj/kg of working fluid and using variable specific heats determine the work produced per mass of working fluid
