The difference I observed between appliances and chargers.I am no electrical and electronic engineer. I am studying chemical engineering and I know only the basics about electronics. But I made an observation. Its a shame that I made this observation this late. Maybe I was taking things for granted.
Anyway, I see that charger wires always have two plug pins and the appliances come with three plug pins.
Did you notice that? You might have.
And I have a general theory about it.
Because appliances need a neutral wire in addition to the charge wires, + and -.
Whereas chargers don't, they supply DC current to the battery I believe.
But all appliances,run on A.C..
So this was my puny observation.
Can't say I'm really proud of my observation.
