**This is more a general understanding question rather than a homework question** 1. The problem statement, all variables and given/known data So when you comb your hair trillions of electrons get transferred from your hair to your comb. So when trillions of electrons go missing how is your body able to maintain a neutral charge? 2. Relevant equations I'm not certain that your body maintains a neutral charge; it was just said by my teacher in class. 3. The attempt at a solution Perhaps because your grounded? With respects to the size and amount of electrons, perhaps a trillion of them is not very many so your body can balance it.
