Unregulated power supply

Use a transformer for the experiment.

here is a description of the transformer.

Half-Wave Rectifier Circuit

1.)Consider building circuit below.

Determine the components needed in order to make the output ripple have a [math]\Delta V[/math] less than 1 Volt.

List the components below and show your instructor the output observed on the scope and sketch it below.

Determine the components needed in order to make the above circuit's output ripple have a [math]\Delta V[/math] less than 0.5 Volt.

List the components below and show your instructor the output observed on the scope and sketch it below.

-.) Choose R in the above circuit so the low-pass filter breakpoint is less than 60 Hz.
-.) Measure the quantities below  using at least 4 different load resistors.

-<math>P_L</math> = power dissipated by the load resistor (don't exceed resistor power rating)
-<math>V_D</math> = output voltage
-.) Explain why the ripple amplitude increases as I_L increases.
