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?

Question

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.

Answer 1

When you feel a buzz or tingle from electricity, you’re feeling the current

A USB port operates on about 5V (small). The resistance of your finger (assuming it’s dry) isn’t a very small amount. This results in a small amount of current, too small to feel.

A USB port also just doesn’t provide enough power to output a current that we would normally feel
