Homework Statement



A half wave rectifier is supplying a load current of 100 mA. The input frequency is 60 Hz. Find the capacitor value required to limit the ripple ot 160 mVpp.

Really... I can solve this I'm sure... But I'm wondering what formula I need to use... I've never been shown one in class, and I don't have a textbook, so a little help with a formula would be nice...

I think the equation you're looking for is [tex]V_r=I_{dc}/fC[/tex].
Where Vr is the ripple voltage, Idc is the direct current, f is the frequency of the supply voltage, and C is the capacitance. But I would do a search for something like "half-wave rectifier capacitor filter" to learn about it and be sure that you agree with it. OK? I don't want to mislead you.
