Electricity is not a thing. It is not an object. Electricity is an event. It's like when something is happening. Electricity is the movement of electrons.
Electrons are a part of all atoms.
When they move from one atom to another, the energy of that movement is what we call electricity. So to make electricity, you have to make that event happen. You have to make that movement. Do not go all the way to the plate's center. Leave an inch or so uncut.
