Ch.15 Flashcards
A particle with equal amounts of positive charge and negative charge
electrically neutral
The condition of having an unbalanced amount of positive charge or negative charge
electrically charged
The loss of an unbalanced electric charge
electric discharge
A material in which electric charges cannot easily move
electric insulator
A material in which electric charges move easily
electric conductor
The force that two electrically charged objects apply to each other
electric force
This invisible region around any charged object is where an electric force is applied
electric field
It is the movement of electrically charged particles, such as electrons
electric current
It is a closed, or complete, path in which an electric current flows
electric circuit
It is a measure of how difficult it is for an electric current to flow in a material
electric resistance
Are machines that transform mechanical energy into electric energy
generators
Through an electric circuit is the amount of energy used to move one coulomb of electrons through the circuit.
voltage
is an object that attracts iron and other materials that have magnetic qualities similar to iron
magnet
Any material that a magnet attracts
magnetic material
Is a push or a pull a magnetic field applies to either a magnetic material or an electric current
magnetic force
It is a region in a magnetic material in which the magnetic fields of the atoms all point in the same direction
magnetic domain
A temporary magnet made with a current-carrying wire coil wrapped around a magnetic core
electromagnet
