Set up a breadboard with a 10k potentiometer as a voltage divider using the wiper as the output pin. Connect an LED and a 560Ω resistor in series to the potentiometer's output pin.
Part 1: Connect a DC power supply to the input and set it to 10V. Slowly adjust the potentiometer to determine how much voltage and current is needed to turn on the LED. Measure the voltage and current using the digital multimeter.
Part 2: Disconnect the DC power supply from the input and connect the function generator to the input. Connect the oscilloscope probes to both the input and output of the potentiometer to display the waveforms. Set the function generator to a sine wave with a DC offset that will turn the LED on and off. Then try a square wave.
