In-lab Tasks:

1. Build the power supply circuit first without the voltage regulator and 1000 $\mu$F capacitor. Use the oscilloscope to view the voltage waveform at node $c$. Sketch this waveform in your lab book.
2. Now add the capacitor to your circuit, use the oscilloscope to view the voltage waveform at node $c$. Again include a sketch of what you see in the lab notebook.
3. Add the zener-diode regulator circuit and measure the output voltage as a function of load resistances between $10$ kohms and 100 ohms. You should at least use resistance values of 10 kohm, 4.7 kohm, 1 kohm, 470 ohm, 100 ohms. Note that you'll need to use resistors that have higher power ratings than you've used in the past.
4. Remove the zener-diode circuit and add the voltage regulator circuit. Repeat the preceding task for this circuit.
5. Now connect your power supply (using the voltage regulator) to your previous lab circuit. Have the TA check your final design. It should now run without having to be connected to be bench power supply.
