Question | Answer |
---|---|
electric force | the attraction or repulsion between electric charges |
electric field | the region around a charged object where the object's electric force interacts with other charged objects |
static electricity | a buildup of charges on an object |
conservation of charge | the law that states that charges are neither created nor destroyed but only transferred from one material to another |
friction | a method of charging an object by rubbing it against another object; the force that one object exerts on another when the two rub against each other |
conduction | a method of charging an object by allowing electrons to flow by direct contact from one object to another object |
induction | a method of charging an object by means of the electric field of another object; the objects have no direct contact |
static discharge | the loss of static electricity as electric charges transfer from one object to another |
electric current | the continuous flow of electric charges through a material |
electric circuit | a complete, unbroken path through which electric charges can flow |
conductor | a material through which charges can easily flow |
insulator | a material through which charges cannot easily flow |
voltage | the difference in electrical potential energy between two places in a circuit |
voltage source | a device that creates an electrical potential energy difference in an electric circuit; batteries and generators are voltage sources |
resistance | the measurement of how difficult it is for charges to flow through a material |
