When a charged object touches a conductor (like a door knob): b. the negative charges move to the conductor and exit the object.
According to the law of electrostatic forces, like charges attract each other and unlike charges repel one another.
In Science, the direction of current (electrons) flow is typically from the anode (positive side) to the cathode (negative side) in an electrical circuit.
In this context, when a charged object such as an electric foil touches a conductor (like a door knob), the negative charges on the charged object are transferred (moved) to the conductor and exit the object.
Consequently, this leaves the charged object with positive charges only.
