Could you please tell me how a capacitor works in full wave rectifier.How does it filter ac and give dc.

Actually if one clearly obsereve the capacitor working with AC and DC , it is observable that with DC the capacitor just charged and then connection breaks when it is fully charged( thats why we say that it stop DC) and with AC capacitor works continously works connection doesnt breaks and current varies with sin wave function(so we say that it allows AC ). It is connected in parallel with the rectifier.
