If you were wearing the sweater shown and rubbed your hand on it, you too would gain some negative charge on your hand. Then when you directly touch a metal conductor, like a door knob, you will feel a shock. This is called Conduction. From this scenario, where does the negative charge go when you touch a door knob?
When you touch a door knob, the negative charge that has accumulated on your hand due to rubbing it on the sweater is transferred to the metal conductor, which is the door knob in this case. This transfer of electric charge from one object to another is called conduction. So, the negative charge from your hand flows through the door knob and is distributed throughout the metal conductor.
