Implement a PT100, represented as a resistor that changes from 80 Ohms at 0 °C to 120 Ohms at 100 °C with a slider. 

Please use a current source to run a current of 5 mA through the PT100.

Then use unity gain amplifiers and a differential amplifier to achieve an output of 15V maximum at 100°C. 

Use a summing amplifier to modify the lower end of the range to 0 V. 

Export your solution to text and upload it on Moodle (no grading, but feedback).

Simulate a string of LED lights with 5 LEDs in the Falstad Circuit Simulator.

Dimension the voltage source so that you can set up voltage stabilisation with a Zener diode.

The LEDs should operate with a current flow of approx. 50mA.

Export the simulation as text and submit the text as your solution.

As before, no copied solutions.

Please design a voltage divider in the Falstad Circuit Simulator that generates an output voltage of 9 V from a supply voltage of 12 V.

Use this output voltage to supply a light-emitting diode with a current-limiting resistor. Select the current-limiting resistor so that a current of 30 mA flows through the LED.

Export the circuit as text and paste this text into your answer. No copied solutions; if two texts are identical, both will receive 0 points.
