If I remember correctly, which I barely do bcuz I dont listen much, electrons flow in the direction where in a positive charge move (or something like that)
What triggers them to move?
Well it's mainly because due to the difference between the positove and negative terminals/energies (voltage) that causes the charge (electrons :D) to move, in simple terms its bcuz of Electrical Pressure... Or was it electric pressure? Lol
Where do they go?
They always exist by moving through our circuits and it is a part of an atom (and molecules)
Oh and circuits (dunno if i said this right) are made up of our atoms and molecules. Yeah
