Half-Wave Rectifier Circuit

1.)Consider building circuit below.

TF EIM Lab10 HW Rectifier.png

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

The output ripple can be found by [math]\Delta V=\frac{I\Delta t}{C}[/math]

I have used the following components and input parameters:

[math]R = 96.9\ k\Omega[/math]
[math]R_L = 98.7\ k\Omega[/math]
[math]R_{scope} = 1\ M\Omega[/math]
[math]C = 2.2\ uF[/math]
[math]\Delta t = 17\ ms[/math] which corresponds to 60 Hz
[math]V_{in} = 24\ V[/math]


The current through the circuit can be found as [math]I = \frac{V_{in}}{R_{tot}}[/math]

where {math}R_{tot} = R + \frac{R_L \cdot \frac{1}{j\omega C}}{R_L + \frac{1}{j\omega C}}{/math}


So my output ripple becomes </math>\Delta V = \frac{}{}</math>

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.
