Voltage controlled current source. for a photoplethysmogram amplifier (which you will learn about later in the class), you will need to design a high quality, precision current source to drive the leds to output light into the body. specifically, you will need to output the following current into the led: i(t) = 5ma + 2ma * cos(2pi1000t). your teammate on the project has created a very precise voltage output using an oscillator circuit with the following waveform: v(t) = 1 v cos(2pi1000*t). design a circuit that will provide the desired current for the led based on the output of this oscillator. what is the output resistance of your circuit (assuming ideal op amp conditions)?

Areheat rankine cycle operates with water as the working fluid. steam enters the first turbine at 8 mpa and 450°c and exits at 0.8 mpa. it is then reheated to 400°c before entering the second turbine, where it exits at 10 kpa. if the amount of work into the pump is 8.04 kj/kg and the net work per cycle produced is 1410.25 kj/kg, determine the thermal efficiency of the cycle.
