De-coupling capacitor and Bulk capacitor

A bulk capacitor is used to prevent the output of a supply from dropping too far during the periods when current is not available. For line-powered linear supplies, this would occur during the periods (say, 10s of msec) that the line voltage is near zero. Depending on the application, it will be something like 10-100µF (sometimes more) and
