A friend of mine brought a little device he made its a bridge rectifier fed straight off the mains then fed into a 900 uF capacitor the purpose of this little device is to try to make a CFL stay on for 10 seconds I don't know why it's his project. We tried this device out and after a few switch ons it popped a 5 amp fuse in the feed to my test bench so the question is what would be the charge current for a 900 uF capacitor? It made the ammeter in the feed to the test board kick up. So is there a way to work it out?
Is this a sensible idea? The compact fluorescent lamp is designed to run on A.C. not D.C. A capacitor will discharge and supply a D.C. current. Try charging the capacitor through a resistor to limit the high charge current.
