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?
Hundreds of amps no wonder I had slight burning on the plug pins I will see if I can get hold of a LED light to try what would be a good brand or model to try? I'm guessing it would need to be one with either a SMPSU or resistive dropper rather than a capacitor dropper which I don't imagine would work on DC
