    Dear all,

    I have an amusing experiment with my smart phone charger. That is, after charging it fully, I connect its input and output toghether, and get surprise result.
    Could you see in my youtube clip and give your explanation here



    Thanks

    The explanation is that you connected its input to its output.

    Maybe the electrons get tired of going around and around in circles, and eventually give up in disgust?

    Yes, the light is red as a signal of charging. In fact it is discharged

    I'm sure the circuit is as confused as I am as to why you would do that. :eek:

    Next time, try something that isn't obviously useless.
