Electricity Vocab Flashcards
Static electricity
The accumulation of excess electric charge on an object.
Law of conservation of charge
Charge can be transferred from object to object, but it cannot be created or destroyed.
Conductor
A material in which electrons are able to 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
The rearrangement of electrons on a neutral object caused by a nearby charged object.
Electric current
The net movement of electric charges in a single direction.
Voltage difference
The force that causes electric charges to flow.
Circuit
A closed path that electric current follows.
Resistance
The tendency for a material to oppose the flow of electrons.
Ohm’s law
The current in a circuit equals the voltage difference divided by the resistance.
Parallel circuit
Contains two or more branches for current to move through.
Series circuit
The current has only one loop to flow through.
Electric power
The rate at which electrical energy is converted to another form of energy.
Wet-cell battery
Wet cell batteries have a pool of liquid electrolytes.
