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.

Full-Wave Rectifier Circuit

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.

Full-Wave Rectifier Bridge Circuit

1.) Choose R in the above circuit so the low-pass filter breakpoint is less than 60 Hz.

2.) Measure the quantities below using at least 4 different load resistors.

[math]R_L[/math]	[math]I_L[/math]	[math]P_L[/math]	[math]V_D[/math]	[math]V_{ripple}[/math]

[math]P_L[/math] = power dissipated by the load resistor (don't exceed resistor power rating) [math]V_D[/math] = output voltage

3.) Explain why the ripple amplitude increases as I_L increases.
