Physics:Leakage current

From HandWiki

The unwanted current leaking between two electrodes under voltage. In detectors, leakage currents can be observed in wire or semiconductor detectors, without ionization caused by the passage of a charged particle. Radiation damage can increase the leakage current, which translates into a decrease of the signal-to-noise ratio.

Leakage current has, of course, a wider meaning, like when occurring with improperly grounded electrical equipment; leakage currents are also relevant in the operation of semiconductor circuits, particularly at high temperatures.
