Cool. Now I understand what a #ground (called #earth in G.B.) is with #electricity :
The entire planet is being used to complete the electrical #circuit !
There’s still a #loop but instead of using copper wire, you just stick big copper pole in the ground. The Earth does the rest. As long as each side of the circuit is grounded, the circle is complete.
let the circle… be unbroken… by and by…. – love this book #CODE no wonder it got 5 stars.
