Issue with my charger

[thinhnghiem]

Dear all,

 

s weknow, the movable charger for smart phone has two ports: Input and output

 

when we do the charging by plugging the socket with the input of the charger, light turns red to show that it is in progress

When the charger is full, the light turns green

What happens if the input and output of the charger are connect by themselves

The light turns red as if this device is being charged with power. In fact, electrical power is being discharged

We never see the light turning green. Instead, when the discharging ends, light is turned off. How do we explain this phenomenon?

You need to ask yourself how the charger knows how much charge is in the cells.

 

You'll then want to ask how you can measure voltage.

 

Then you'll know why plugging it into itself produces oddresultss.

Is good to see people curiose i will try to explain it simple.

Think eletricity as a river and a river always have a flow.

That flow is called volts.

So what happens when you charge your phone?

You input the connector and the connector recharge the batery of your phone.

In other words think like a Windmill, as long as the Water runs on it you can make bread, and then you can eat it:)

However if you dont have enough presure of the Water(volts) because your river now is splitted in 2 you wont be able to produce bread so rip that ligt.

 

That was the soft version, what realy happens is that the Led use the energy of the batery but since you are removing energy from that same batery it will never be able to get charge ans eventualy the batery wont be able to give energy to the led so it will turn off.
