When a negatively charged object makes contact with a positively charged object, an interesting interaction occurs. The excess electrons from the negatively charged object are attracted to the positively charged one due to the difference in charge. This results in an electron flow from the negatively charged object to the positively charged object.
The process continues until the charges on both objects equalize, meaning that the negative object loses some electrons and the positive object gains them. This equalization of charge is known as discharge. Once they reach equilibrium, both objects will have either a neutral charge or smaller magnitudes of remaining charge, depending on their original charges and the amount of electron flow.
This phenomenon explains why you might feel a small shock when touching a metal object after walking on a carpet. Your body might accumulate a negative charge, and upon contact with a neutral or positively charged object, the electrons flow to equalize the charge difference, resulting in that little jolt.
