(A) n: the fundamental unit of electrical current;1 ampere = 6.28 x 1018 electrons passing through the circuit per second. One ampere delivers I coulomb in 1 second. ampere-hour n: a unit of electricity equal to the amount produced in 1 hour by a flow of I ampere. See ampere.

n: the product of volts and amperes in an AC circuit when voltage and current are measured separately. If voltage and current are not in phase, apparent power is greater than true power.

n: contacts that interrupt the current in the primary circuit of the ignition system in a spark-ignition engine.

n: a carbon block used to make an electrical connection between the rotor of a generator or motor and a circuit.

n: an electrical device that. when wired in the line of an electrical circuit, stores a charge of electricity and returns the charge to the line when certain electrical conditions occur. Also called a condenser.

n: a complete electrical path from one terminal of a source of electricity to me other, usually connected to a load. When me circuit is closed, electric current flows through it;when it is opened, me current flow stops.

n: 1. a life-support system in which the gas is recycled continually while the carbon dioxide is removed and oxygen added periodically. 2. a television installation in which the signal is transmitted by wire to a limited number of receivers.

n: provision of a supplemental device, circuit. or special materials to counteract known sources of error.

n: 1. a section of pipe or fitting used to join pipe to pipe or to a vessel. 2. a place in electrical circuits where wires join.3.the action of adding a joint of pipe to the drill stem as drilling progresses.

n: the joining of a section of drilling pipe to another

n: 1. a vessel or piece of equipment in which two or more substances are brought together. 2. a switch used to open or close an electric circuit.
