If the dryer was grounded, and the breaker noticed a direct short to ground, it would trip almost immediately, right? So the question is that if it wasn't a direct 0 ohm short, but instead a human body, that would be like 1 million ohms to ground right? So would that body have to get like 30 amps through that body to trip the breaker on a non GFCI situation?

If it were to trip, it would trip within a few cycles of the ground fault and your electricity operates at 60 cycles a second here in the US.
There is no way to know what a human body's impedance is. It all depends on the path the electricity takes. The electricity could start in your hand and go out your foot, or it may go in one finger and out another finger.

First, If the ground was working it would handle the fault. The real question seems to be how much current would go through you prior to tripping the breaker, the answer is almost 100 amps instantaneous, that amount doesn't flow long, A second is a long time when electrons are dumping into a human,an amp is something like 1x10 to the 12th power times a hundred. This amount could cause you an inadvertent bowel movement.

all of these answers are quite fascinating, but...the easy answer is that breakers "trip" when a short appears and causes heat. inside a breaker are two strips of metal. when exposed to heat they bend. one bends one way and one bends the other way. when this happens, the breaker opens, "trips" the circuit and the flow of electricity stops. when it cools back down, the metal strips return to their normal position, and the flow of electricity will return to normal once reset. the answer is no. until you burn and bleed through your shoes and cause a direct ground, the breaker will continue to flow, and more than likely, kill you.

it would need to exceed the amperage on the breaker. keep in mind that it is 220V. so... 220V * 30A = 660Watts.
the amount of resistance that a person would have would depend on many many variables like type of shoes, amount of electrolytes intheir body, etc.

It might not even trip - it may just make a crispy critter out of
you - dont try it.

It's not the volts that kill you... it's the AMPS!

Don't even try it,
