Hello, I was experimenting with some LEDs to do a night lamp, when something really weird happened. One of the LEDs, the only white one that I have, if it was grounded, or connected to Vcc, and I thought the other electrode with my finger, the LED would like up, not as if the battery was connected, but a very faint light that could be easily seen. The voltage came from a cell charger that outputs 5V, I stripped the wires and used it as my voltage source. I thought this might happen because it is grounded to the mains (via the charger?), but when I connected it to Vcc and touch it with my finger on the cathode it still lighted up.
Any ideas? This is very weird. I also tried with other LEDs and didn't happen.
