There are certain moments in life I wish I had actually listened to the teachers at class instead of dreaming about the knight in shiny armour.
The knight never came ( must be stuck in a traffic jam??)and I am in the process of becoming an idiot, at least in front of my children.
All I was trying to do was to explain why the birds sitting on a transmission line don’t get zapped.
Technically it is simple, there is no circuit unless the poor bird touched the earth wire.
I explained the way current moves from high to low and the fact that both feet of the bird touches the wire makes it possible for the current to bypass the bird’s body!
But then my child wants to know why there is no electricity going through the bird, since its body is a conduit for electricity.( otherwise it won’t get zapped!)
I know it has something to do with the birds body being at the same voltage as the wire..What I don’t know is, why it is so..and before I get fried, help me.
