Filter capacitor value ?
What value of filter capacitor should be used after bridge rectifier for an unregulated power supply of 12V/2A.
Right now I am using 4700uF capacitor but voltage begins to drop as current increases beyond 1A.
What is the relation between output current and filter capacitor value? How can I calculate it?
