How do I caluclate which capacitor to use as a filter after the brdige rectifier using the 18Vpk A.C. 50 Hz as a source?
Q = C * V
which after calculus, and constant dC/dT, and a bit of algebra, becomes
I = C * dV/dT.
Making the 4 variables be &quot;1&quot; provides an equality.
You can substitute different values, for any 3, and compute the 4rth.
