Chapter 15 Flashcards
A particle with equal amounts of positive charge and negitive charge
electrically neutral
has an unbalanced amount of positive charge or negitive charge
electrically charged
The loss of an unbalanced electric charge
eletrical discharge
A material in which electric charges cannot easliy move
electric insulator
A material in which electric charges easily
electric conductor
The force that two electrically charged objects apply to each other
electric force
this invisible region around any charged object where an eletrcic force is applied
eletrcic field
is the movement of electrically charged particle such as electrons
electric current
is a closed or complete path in which an eletric current flows
eletric circuit
are machines that transform mechanical energy into electrical energy
generator
a measure of how difficult it is for an eletrcic current to flow in a material
eletric resistance
an eletric circuit is the amount of energy used to move one coulomb of electrons through the circuit
voltage
an object that attracts iron and other materials that have magnetic qualities similar to iron
magnet
Any material that a magnet attracts to is a
magnetic material
is a push or a pull a magnetic field applies to either a magnetic material or an eletrcic current
magnetic force
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 is an
electromagnet
