4. Electronics the region in a transistor into which charge carriers flow from the base
in agricultural irrigation, a drainage pipe or canal that receives water from the regulating part of an irrigation network (drainage gutters) and sends it out of the area being drained.
A semiconductive region through which a primary flow of charge carriers leaves the base of a transistor; the electrode or terminal connected to this region is also called the collector.
An electrode that collects electrons or ions which have completed their functions within an electron tube; a collector receives electrons after they have done useful work, whereas an anode receives electrons whose useful work is to be done outside the tube. Also known as electron collector.
A class of instruments employed to determine the electric potential at a point in the atmosphere, and ultimately the atmospheric electric field; all collectors consist of some device for rapidly bringing a conductor to the same potential as the air immediately surrounding it, plus some form of electrometer for measuring the difference in potential between the equilibrated collector and the earth itself; collectors differ widely in their speed of response to atmospheric potential changes.
A device designed to absorb radiation from the sun and transfer this energy to a fluid which passes through the collector.
ii. A device sometimes incorporated into the fuel system of a gas turbine engine to store and release fuel under pressure as an aid in starting. Also called a collector.
iii. A device for storing fuel in a fuel tank for inverted flying.
iv. In pneumatic and oxygen systems, the reservoir where compressed air or oxygen is stored.
v. An electrical storage battery that can be recharged.
