Flashcards: Charging by Friction, Conduction, Direct Contact, Induction
Charging By Friction
Transfer of electrons from one object to another by rubbing.
Charging By Conduction
Electrons transfer from object that has negative charges to positive charged object.
Charging by Induction
Electrons move to one part of an object because it is in the electric field of another object.
Static Discharge
The loss of static has negative charge transfer from one object to another.
Three methods of charging
Friction, Conduction and Induction
Charging By Friction Example
Clothes rubbing together in a dryer, feet rubbing on a carpet.
Charging by Conduction Example
Foot becomes charged by friction, rest of body becomes charged because it has contact with foot.
Charging by Induction Example
Electrons on fingertips cause electrons on doorknob to move away, leaving doorknob with a positive charge.
Electrons
They carry the electric charge around the circuit; have a negative charge
electric current
The continuous flow of electric charges through a material
current
A flow of electric charge. A flow of electrons
electricity
A form of energy used in telegraphy from the 1840s on and for lighting, industrial motors, and railroads beginning in the 1880s.
