i have read around the forum that the speed of electrons in a conductor is somewhat 1mm/s
if that is true , then how do galvanic cells operate ? by that rate , about 1000 electrons would come out of the conductor / sec , not only this , but it would seem like the velocity of electrons is irrelevant of the current intensity * i know i should not be treating charges and electrons the same *
but for a current of 1 ampere , that's 1 couloumb / sec , 6.24*10^18 electrons * if i recall correctly * must come out of the conductor to precepitate 1.118 grams of silver * the amount of silver precipiptated by the passage of a couloumb in a solution of silver * so it does not make any sense
( this might seem like it should be posted somewhere in chemistry forum , but i am asking about a physical phenomena which is how the electrons travel in a conductor "
