Electric Forces and Fields
Term | Definition |
---|---|
Charge | An imbalance of electrons as compared to protons. |
Conductors | Material that transfers charge easily |
Insulators | Material that does not transfer charge easily. |
Conduction | The process of charging a neutral conductor by touching it with a charged conductor. |
Electric Field | A region in space around a charged object in which a stationary charged object experiences an electric force because of its charge. |
Coulomb's Law | The electrical force between two charged objects is directly proportional to the product of the quantity of charge on the objects and inversely proportional to the square of the separation distance between the two objects. |
Potential Difference | The difference between the potentials of two points in an electric field measured in volts. |
Capacitance | The ability of a conductor to store energy in the form of electrically separated charges. |
Induction | The process of charging a conductor by bringing it near another charged object and then grounding the conductor. |
Polarization | slight relative shift of positive and negative electric charge in opposite directions within an insulator, induced by an external electric field. |
emf | "electromotive force" or energy per unit charge supplied by a source of electric current. |
Grounding | The process of removing the excess charge on an object by means of the transfer of electrons between it and another object of substantial size. |
