Why do humans feel electric shocks? So, when a person or any object has extra electrons, it creates a negative charge. These electrons thus get attracted to positive electrons (as opposite attracts) of another object or person and vice versa. The shock that we feel sometimes is the result of the quick movement of these electrons.
