See the attached pdf schematic
I understand a capacitor can be used as a filter but how does it reduce the ripple from a rectified AC signal?
It's connected in parallel so I understand it won't just charge up and then act as an open like it would in a standard DC circuit. Is it safe to say the ripple current is like a pulsating DC current? Which would be comparable to a very low frequency AC signal?
I understand how capacitive reactance relates to frequency so does it make sense to say the rectified AC signal is like a pulsating DC signal before the capacitor "cleans up" the signal?
Also, what kind of equipment would use this type of schematic? I'm guessing its some sort of small household appliance that requires a DC input.
Any help is greatly appreciated,
Thanks
