current (redirected from pacemaker current)

current

(1) The flow of electrons through a circuit. Measured in "amperes." See amp and voltage.

(2) The latest version or model.

(3) (Current) An earlier Windows PIM from IBM that included a calendar, address book, phone dialer, outliner, word processor and Gantt charts for project tracking. It was revised by its developer, Jensen-Jones Inc., Red Bank, NJ, into a new package called Commence.

(electricity)

The net transfer of electric charge per unit time; a specialization of the physics definition. Also known as electric current.

(electronics)

current - The quantity of charge per unit time, measured in Amperes (Amps, A). By historical convention, the sign of current is positive for currents flowing from positive to negative potential, but experience indicates that electrons are negatively charged and flow in the opposite direction.
