Module 6 Electricity

Static Electricity

The accumulation of excess electric charge on an object

Law of Conservation of Charge

Law that states that charge can be transferred from object to object, but it cannot be created or destroyed

Electric Field

Field surrounding every electric charge and exerts the force that causes other electric charges to be attracted or repelled

Conductor

A material through which electrons move easily

Insulator

A material in which electrons are not able to move easily

Charging by Contact

The process of transferring charge by touching or rubbing

Charging by Induction

When a nearby charged object causes the rearrangement of electrons on a neutral object

Electroscope

A device that can detect electric charge

Electric Current

The net movement of electric charges in a single direction

Voltage Difference

The force that causes electric charges to flow

Electric Circuit

A closed path that electric current follows

Resistance

The tendency for a material to resist the flow of electrons and to convert electrical energy into other forms of energy

Ohm's Law

The current in a circuit equals the voltage difference divided by the resistance

Series Circuit

An electric circuit with only one branch

Electrical Power

The rate at which electrical energy is converted to another form of energy
