heat is transferred by electromagnetic waves
direct transfer of heat from on object to another
a circuit that has two or more paths through which electric charges can flow
a thin, coiled wire that can get very hot without melting
heat is transferred by currents in fluids
when positive and negative charges no longer balance
a material through which an electric current or heat can move easily
a circuit that allows electric charges to flow in only 1 path
a material through which an electric charge and heat do not move easily
an electric charge in motion
