    Hi, I am having problems understanding how exactly electricity moves in matter. In an other post, I have asked if energy was heat, the answer given to me was yes, but how does electric current pass through matter?

    Do negatively charged electrons simply move towards the +1 (positively charged cathode)?

    Do they hit other electrons and drag them on their way to the positively charged cathode?

    What if an electron hits the nuclei of the atom; what happens?

    Alternate energy... or should we rather say alternate life?

    Are you interested in scientific high school projects? If you are, please contact me!

    well, since its easiest to explain for normal metals i´ll do that
    Metals have delocelsied electrons, that doesnt belong to any specefic atoms but is shared by all atoms. when a current is put on the metal one side will become negativly charged and the toehr posetivly charged. electrons then begin moving toward the posetive end and as they move more electrons comes out of the negative end to replace in equal rate

    Do they hit other electrons and drag them on their way to the positively charged cathode?
    yes, thats resistence. thats why also things get hotter when a current is going throu it

    What if an electron hits the nuclei of the atom; what happens?
    it dont. since neither one has a specefic radius it wont hit. and their position isnt specefic either becuase if quantum mechanic
