What are the 3 ways that electric charge can be transferred?

• A. Conduction, Induction and Charging by Friction
• B. Conduction, Convection and Radiation
• C. Induction and Friction Only
• D. Friction Alone

Answer: (A)

Charge can move between objects in three main ways: conduction, friction (charging by rubbing), and induction. Conduction happens when objects touch and electrons flow from the one at higher potential to the one at lower, leaving both at a common voltage or transferring net charge to the second object. Friction involves rubbing two materials together; because different materials hold onto electrons with different strengths, electrons can be transferred from one material to the other, giving opposite charges to the two surfaces. Induction uses the electric field from a nearby charged object to rearrange charges within a neutral body; no electrons necessarily leave the neutral object, but nearby charges cause a separation of charges, and with a grounding path you can end up with a net charge on the object when the external influence is removed. These three capture the standard ways charge can be transferred, while convection and radiation are energy-transfer processes, not charge-transfer mechanisms.
