Hi all,
I can't get how to compute the value of C to have let's say a 10% Voltage Ripple.
This is the example on what i'm studying:
So V1 is a 4 V peak to peak sinusoidal wave at 1kHz.
I have to add a capacitor in parallalel to R1 to get a 10% Ripple Voltage
I wanted to use the formula:
\( V_{rpp} = \frac {I_{load}}{fC} \)
From simulation (without capacitor) I got that \(V_{o max} = 1.351V\) and \(I_{R1} = 600 uA\)
I was wondering if the Iload in the formula is this one or not. And ripple voltage should be 10% of 1.351? Or 10% of Vdc?
