You have got to love electricity. It’s there… but you can’t see it, hear it or smell it. You can feel it… oh yes.
But then, sometimes, something happens that allow us to “see” electricity. This is an oldie but a goody.
And that, my friends, is electricity!
What happens is that, when the isolator opens the electricity attempts to continue flowing. That causes the arc to start. When the arc develops the air is ionised making the flow of electricity through the air easier. That is why the arc keeps on going even after the isolator is fully open!
