Why is it safe to touch the electricity-outputting end of our phone and computer chargers with no sort of electric shock on us as opposed to other dangerous electrical outputs?

Exactly as stated in the title. All my life I’ve been able to touch my phone or computer’s electrical charger output (accidentally or for whatever the reason) with no sort of “buzz” or feeling from the electricity going through the output. At least that has always been my experience with it.

Just in case: Don’t intentionally try this of course.

* You usually need to complete a circuit (a round trip for electricity) to get shocked.
* Some plugs can easilly be attached to things (and hence more easily accidentally complete a circuit when you don’t want to), like alligator clips or bare wires or the wires inside a machine.
* However, many plugs for consumer electronics are designed so that it is hard to do that accidentally (the inside+outside of a charging cable, or two specific prongs embedded inside the wall).
* Many consumer electronics operate at low voltages, which has trouble getting past the barrier of your skin. If you bypass the skin, you canget shocked. e.g. licking a 9V battery will shock you, but touching it won’t (or rather, it will shock you so weakly you don’t notice). So, if you cut open your chest, and plugged a laptop charger directly into the pool of blood forming in your chest, I reckon that would shock you, as your blood seeps into the socket and touches both the inside and outside of the laptop charger, hence electrifying your blood.
