Electricity

What is the accumulation of excess electric charge on an object?

• Thermal Energy

• Static Electricity

• Electric Field

• Variable Electricity

As you walk across the carpet, your shoes collect electrons from the carpet, however, the total charge in this system doesn't change. What law does this demonstrate?

• Newton's First Law

• Law of Conservation of Matter

• Newton's Second Law

• Law of Conservation of Charge

This is responsible for electric forces exerted on objects that aren't touching each other. It is shown in the image.

• Electric Field

• Conducting Field

• Law of Conservation of Charge

• Insulating Field

• Charges

This process transfers charge by touching or rubbing of two objects. Electrons are transferred.

• Charging by Electric Field

• Charging by Contact

• Charging by Electrons

• Charging by Induction

This process of charging results in the rearrangement of electrons on a neutral object. It is shown in the image.
