	==Electronics==
	In electronics, leakage is a property of dielectric materials used in ], also known as ''dielectric leakage''. It is a result of the ] material having a finite ] and therefore carrying a ] (known as the ''leakage current'') due to the ] across it. This results in capacitors discharging themselves over time (analagous to a bucket full of water with a hole in it, the size of the hole relating to the amount of leakage).

	The dielectric material can be selected to have low leakage, which may be required for some electronics applications such as ] circuits.

	==Retail==
	Retail leakage occurs when members of a community spend money outside that community or when money spent inside that community is transferred outside the community. For example, crossing a border to buy goods forgoes the same purchase that could have been made inside the community.

	Many ]s have high leakages rates due to the transferring of sales ] to a corporate headquarters. Also, in retail, leakage can mean the loss of ] without a compensating stream of revenue, for example, a till operator stealing from a till, or a shoplifter stealing stock.

	== Semiconductors ==
	In semiconductor devices, leakage is a ] phenomenon where mobile charge carriers (electrons or holes) ] through an insulating region. Leakage increases ]ly as the thickness of the insulating region decreases. Tunneling leakage can also happen across semiconductor junctions between heavily doped P-type and N-type semicondutors. Other than tunneling via the gate insulator or junctions, carriers can also leak between source and drain terminals of a ] (MOS) transistor. This is called sub-threshold leakage. The primary source of leakage occurs inside ]s, but electrons can also leak between interconnects. Leakage increases power consumption and if sufficiently large can cause complete circuit failure.

	Leakage is currently one of the main factors limiting increased processor performance. Efforts to minimize leakage include the use of ], ] dielectrics, and/or stronger ] levels in the semiconductor. Leakage reduction to continue ] will not only require new material solutions but also proper system design. A good overview of leakage and leakage reduction methods are explained in

	==Sound Recording==
	] is at its optimum when there is sufficient isolation between individual tracks, to allow for freedom in ] each track to a desired sound level. Reasonable isolation can be achieved (even in a live recording) by careful microphone placement, or by the separation of sound sources. Sound leakage can limit or even ruin the remixing and overdubbing potentials for a multitrack recording, when one sound interferes with another sound on a track.
