so at the most basic level, charged electrons desire to be in a neutral state, if we provide a path for them to travel that is grounded, then they will travel along that path and we will make them do work for us along their way. i am confused as to how they know if a a path is grounded or not, say you make a basic circuit that is not grounded, the charged particles will not travel through the circuit until you have a ground....so how do they just magically know if the circuit is grounded or not? its not like they send scouter particles to verify if its grounded or anything...
also, i dont understand how they know weather a path they will travel is complete or not, for instance, say you have electricity traveling through a copper wire, if you cut that wire in half, then the electricity stops flowing through it, the electricity does not continue traveling through the wire and end up flying out the cut end, they simply dont travel through it anymore....how do they know????
