What’s the difference between and electric field, and what comes out of a wall outlet? How can something be in an electric field but not be electrocuted?

Google tried to explain Coulomb’s Law to me and I don’t understand.

An electric field is a potential field, just like gravity (we’ll ignore Einstein here and stick to Newton). One major difference between them is a gravity field is generated by and affects particles with mass, and an electric field is generated by and affects particles that have a charge.

The voltage (a measure of the “strength” of an electric field) is analogous to the height of the cliff. If you are standing on the edge of the cliff then you have a lot of potential to gain a lot of kinetic energy if you fall over. If you’re not there, or you decide to not go over the cliff, then that potential is just potential and nothing happens. Voltage is the same thing. If a charge isn’t present or can’t move, then the potential for something to happen is there, but nothing does.

Electrocution implies the movement of charges. This would be like you standing under the cliff. You are perfectly safe as long as nothing is on the cliff or decides to go over the edge. If a herd of cows jumps over the cliff they’ll land on you and gravitocute you!

The outlets is like a cow source (electrons in cow costumes?). It has a bunch of cows ready to jump and fall on top of you. You stick a fork in the outlet then you prod those cows to jump out and run fall on you (electrocuting yourself).

Contrary to popular belief, electrons simply don’t move, they stay in the same area and are repeatedly accelerated by the magnetic field that gets completed when a power source and load are close enough, that’s how transformers work and also why wireless charging works such as with toothbrushes,
That’s also why lightning works, wireless charging with wifi works etc

The reason it may not eletrocute you is that air is terribly inefficient and skin is naturally a good insulator
