Charging by contact | which is the transfer of electric charge between objects in contact |
charging by induction | the rearrangement of electric field |
insulators | materials in which electric charges do not move |
conductor | materials in which electric charges can move easily |
static charge | the imbalance of electric charge on an object is called |
electric discharge | is the movement of static charge from one plate to anohter |
electric current | is the flow of electric charges |
electric resistance | the measure of how difficult it is for electrons to flow in an object |
voltage | is a measure of the amount of electrical energy transferred by an electric charge |
series circuit | devices are connected so there is only one closed path for current to follow |
parallel circuit | devices are connected so there is more then one closed path for current to follow. |
magnetic domain | a group of atoms that have their magnetic poles pointing in the same direction is called |
electromagnet | a current carrying wire wrapped around an iron cloe |
electromagnetic induction | the production if an electric current by moving a magnet and a loop relative to each other |
