There is no such thing.
What there is is leakage current, which is the amount of undesired current flow in a branch of an actual circuit when that branch of the equivalent ideal circuit would have no current flow.
Leakage current can also be used to refer to current that occurs on a path where there is no intentional circuit branch (e.g. corona discharge current to the air in a high voltage system).

What is leakage current in transformer?
In low voltage and electronics Leakage Current is any current that flows when the ideal current
What is leakage resistance?
leakage resistance of a resister is type of fault which occurs at a specific voltage across the resister which are undertesting.
Why do you have variation in leakage reactance of induction motor?
leakage reactance in induction motor depends on the reluctance of the path in which the leakage flux is establishing. with the increase in stator current the leakage flux also increases but it cannot maintain linear relationship because of saturation of the leakage flux path, even though current is increasing the flux will not increase and it'll be constant after saturation. this leakage flux links with the stator winding and induces emf which will be opposite to the supply voltage causes drop in applied voltage , the drop in the applied voltage is represented with the leakage reactance. as flux is responsible for the induction of emf , the increase in current does not increase flux after saturation and therefore emf also doesnot increase so the leakage reactance is not constant throughout the machine operation...
Voltage of a diode at which current increases?
In a Silcon diode no current flows in the forward direction (anode to positive voltage) until approximately 0.6 - 0.7Volts is reached. Above this voltage the current rises in line with Ohms Law. In the reverse direction only micro Amps flow (leakage current) In a Germanium diode the threshold is about 0.2 volts and reverse leakage is higher.
Draw and explain the operation of fault voltage ELCB and residual current device?
ELCB means Earth Leakage Circuit Breaker -- it is used to trip the Circuit breaker if any leakage fault occured means

How do you test leakage on equipment?
by measuring the insulation resistance then by usig the formula for finding leakage current leakage current =voltage applied /resistance measured by megger.
Why pmos is always connected to supply voltage vdd?
for reducing the leakage current.

How do you understand the leak in vacuum bottle of vacuum circuit breaker without high voltage test?
Understanding the components of the vacuum bottle, one can be in better position of understanding the leakage. Microprocessor monitors leakage in the Vacuum bottle.
Why apply in dc voltage in winding meggering time?
The DC between windings is analogous to DC on capacitor plates. Windings, like capacitors, require time to charge up to the applied voltage, at which, there will be a constant current. Since Voltage / current= Resistance, the Megohm reading will change/increase until the windings are fully charged to a quiescent, steady leakage current. When current is at a stable leakage level, you will have an accurate reading. xfrmrman
When a voltage source is in series wit three capacitor then what will be the same?
Neither voltage applied to nor current through the capacitors will necessarily be the same when you have a voltage source in series with three capacitors that are in series with each other (transient response), but eventually a leakage current will be the same. Transient analysis will show when the DC source is first applied, Each capacitor will begin storing energy based upon the time constant for that particular capacitor (R*C). If all three capacitors are exactly the same, then the voltage across each will match while they charge up, and will be about 1/3 of the source voltage for each when completely charge. If they are different size capacitors, they will store different amounts, resulting in different voltage drops. In steady state, there will be some leakage current, which is extremely small, that will eventually given enough time be the same through all three capacitors. ANSWER: With different leakage each capacitor will experience a miss much of voltage that will make leakage more pronounced in a vicious loop making it all to fail. There is a solution that is to add an equal resistance across each capacitor to equalize the voltage such that each see the same voltage no matter what.
Why the 3 phase of high voltage conductor or cable transposed?
3 phase cable is transposed to minimize the effect of leakage/capacitance current.
Why not use an ohm meter to check leakage in a wires insulation?
An ohm meter doesn't put out enough voltage, you need to use a megger.
