When conductors with negative charge touch, electrons flow from the object that has a greater negative charge to the object that has less negative charge in the process of conduction.
Step-by-step explanation:
Electronic conductivity is defined as the exchange of charges between two bodies that are conductors by means of exchange and sharing of electrons between themselves.
Electrons are actually responsible for the existence of negative charges in the electricity, and presence of electrons make a body negatively charged and absence of electrons make them positive charged.
When a more negatively charged body touches a less negativity charged body, the electrons from more negatively charged body flows to the body with less negatively charged one, because of more electron density.
