What is surface leakage ?

    what is "surface leakage"?

    when talking about the conductance of glass or some insulator, i often hear that no current will be read going through the glass; rather, if i do read anything on my multimeter, i have been told that what i am reading is "surface leakage"; what is this surface leakage they speak of?

    iScience, Since I haven't learned everything about everything yet, I used Google to find out what is "surface leakage". It took me about eight minutes to get a basic understanding of exactly what it is, why it's important, and how it's measured.

    Moisture condenses on the surface of glass. Dirt contaminates it. The surface becomes a conductive film.
