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 charges on your hand (gained from rubbing against the sweater) will flow from your hand to the metal conductor (door knob) through a process called conduction. The metal conductor, being a good conductor of electricity, allows the charge to easily flow through it. Hence, the negative charge is effectively transferred from your hand to the door knob. This movement of electric charge results in a discharge or a small electric shock that you may feel.
