Intro to Current definitions Flashcards

Study of electric charges in motion, as opposed to electrostatics where charges are stationary.

Flow of electric charge, typically measured in amperes, representing charge passing through a point per unit time.

Direction of current flow assumed to be positive charges, opposite to the actual electron flow.

Voltage between two points that motivates charge movement, also known as electromotive force.

Another term for potential difference, not an actual force, but drives electron movement.

Unit of electric current, equivalent to one coulomb of charge passing a point per second.

Device that stores electrical energy in an electric field, used in the example to calculate current.

Unit of electric charge, equal to 10^-9 coulombs, used in the example calculation.

One thousandth of an ampere, used to measure small currents in the example.

Fundamental charge unit, approximately 1.6 x 10^-19 coulombs, used to calculate electron numbers.

Area through which charge flows, used to define current as charge per time.

Actual movement of electrons, opposite to the direction of conventional current.
