current /cur·rent/ (kur´ent) 1. anything that flows. 2. electric c. action current the current generated in the cell membrane of a nerve or muscle by the action potential. alternating current a current which periodically flows in opposite directions. convection current a current caused by movement by convection of warmer fluid into an area of cooler fluid. direct current a current flowing in one direction only. electric current the stream of electricity that moves along a conductor. Symbol I . galvanic current a steady direct current, especially one produced chemically. current of injury a flow of current to (systolic c. of injury) or from (diastolic c. of injury) the injured region of an ischemic heart, due to regional alteration in transmembrane potential. pacemaker current the small net positive current flowing into certain cardiac cells, such as those of the sinoatrial node, causing them to depolarize. alternating current (AC) [ôl′tərnā′ting] an electric current that reverses direction, according to a consistent sinusoidal pattern. Compare direct current. See also current. current, n a measure of the number of electrons per second that pass a given point on a conductor. current, alternating, n a current that alternately changes its direction of flow. It usually consists of 60 complete cycles/sec. current, coagulating, n an electrical current, delivered by a needle, ball, or other variously shaped points, that coagulates tissue. current dental terminology (CDT), n a listing of descriptive terms and identifying codes developed by the American Dental Association (ADA) for reporting dental services and procedures to dental benefits plans. current, direct, n an electrical current in which the electron flow is in only one direction. current, galvanic, n a direct current created by a battery. current procedural terminology (CPT), n a listing of descriptive terms and identifying codes developed by the American Medical Association (AMA) for reporting practitioner services and procedures to medical plans and medicare. n the maximum current in a roentgen-ray tube that fully uses all electrons that are available at the cathode for the production of roentgen rays. current that which flows; electric transmission in a circuit. alternating current a current that flows in opposite directions sinusoidally. direct current a current whose direction is always the same.

The MGD Termit has an aggregate power of 6 kW; mass, 10 kg; maximum
welding current in standard configuration, 200 A; constant off-load
output voltage, 65 V; welding current regulation range, 10-20 A;
constant output voltage for illumination, electric power tools, 220 ([+
or -]15) V; accumulator batteries 12 V (24 V); recharge voltage 3-100 A;
shutoff protection in 220 V circuits with current overload or short
circuit; direct to alternating current converter option, 220 V, 50 Hz. At the time, George Westinghouse was selling residents of
Manhattan alternating current electricity as a cheaper alternative to
Edison's direct current power. The company's main product is a device that converts
electrical power from alternating current to direct current with the
focus on industrial and telecommunications departments. |
