Leakage inductance
Leakage inductance derives from the electrical property of an imperfectly-coupled transformer whereby each winding behaves as a self-inductance in series with the winding's respective ohmic resistance constant. These four winding constants also interact with the transformer's mutual inductance.
Leakage (electronics)
GRADUAL TRANSFER OF ELECTRICAL ENERGY ACROSS A BOUNDARY NORMALLY VIEWED AS INSULATING
Leakage current; Leakage (semiconductors); Transistor leakage current; Dielectric leakage; Leakage power; Leaking electricity; Leak resistance; Leakage resistance; Leak current
In electronics, leakage is the gradual transfer of electrical energy across a boundary normally viewed as insulating, such as the spontaneous discharge of a charged capacitor, magnetic coupling of a transformer with other components, or flow of current across a transistor in the "off" state or a reverse-polarized diode.
Reactance (psychology)
UNPLEASANT MOTIVATIONAL AROUSAL TO OFFERS, PERSONS, RULES, OR REGULATIONS THAT THREATEN OR ELIMINATE SPECIFIC BEHAVIORAL FREEDOMS
Psychological reactance; Reactance theory
Reactance is an unpleasant motivational reaction to offers, persons, rules, or regulations that threaten or eliminate specific behavioral freedoms. Reactance occurs when an individual feels that an agent is attempting to limit one's choice of response and/or range of alternatives.

Reactance (disambiguation)
¦ noun Physics the non-resistive component of impedance in an AC circuit, arising from inductance and/or capacitance.

Reactance (disambiguation)
·add. ·noun The influence of a coil of wire upon an alternating current passing through it, tending to choke or diminish the current, or the similar influence of a condenser; inductive resistance. Reactance is measured in ohms. The reactance of a circuit is equal to the component of the impressed electro-motive force at right angles to the current divided by the current, that is, the component of the impedance due to the self-inductance or capacity of the circuit.
Leakage (machine learning)
CONCEPT IN MACHINE LEARNING WHERE INFORMATION IS USED THAT WOULD NOT BE AVAILABLE WHEN PREDICTIONS ARE MADE
Data leakage; Target leakage
In statistics and machine learning, leakage (also known as data leakage or target leakage) is the use of information in the model training process which would not be expected to be available at prediction time, causing the predictive scores (metrics) to overestimate the model's utility when run in a production environment.

Leakage
WIKIMEDIA DISAMBIGUATION PAGE
Leakage (disambiguation)
The loss of current from conductors; due to grounding at least at two
places, or to very slight grounding at a great many places, or all along
a line owing to poor insulation. In aerial or pole telegraph lines in
wet weather there is often a very large leakage down the wet poles from
the wire. (See Surface Leakage--Magnetic Leakage.)
Leakage (retail)
RETAIL SALES MADE OUTSIDE OF LOCAL AREA
Sales leakage
Retail leakage occurs when local people spend a larger amount of money on goods than local businesses report in sales, usually due to people traveling to a neighboring town to buy goods. Retail sales leakage occurs when there is unsatisfied demand within the trading area and that the locality should provide extra stores spaces for such type of businesses.

Leakage inductance
Leakage inductance derives from the electrical property of an imperfectly-coupled transformer whereby each winding behaves as a self-inductance in series with the winding's respective ohmic resistance constant. These four winding constants also interact with the transformer's mutual inductance. The winding leakage inductance is due to leakage flux not linking with all turns of each imperfectly-coupled winding.
Leakage reactance is usually the most important element of a power system transformer due to power factor, voltage drop, reactive power consumption and fault current considerations.
Leakage inductance depends on the geometry of the core and the windings. Voltage drop across the leakage reactance results in often undesirable supply regulation with varying transformer load. But it can also be useful for harmonic isolation (attenuating higher frequencies) of some loads.
Leakage inductance applies to any imperfectly-coupled magnetic circuit device including motors.
