Looking for a fluid that's electrically charged: Safe to consume is small amounts?

  1. Oct 27, 2012 #1
    Can anyone tell me some fluids that are electrically charged? And if it would be safe for, lets say, a fly to consume?

    Any charged fluid will discharge once grounded.

    I wanted to give some flies some fluid, like water or something, then give them the same fluid, but this group will be in an environment that has a different electric field.

    Indeed - no liquid has the property of holding a monopole charge.

    Note that a non-grounded fluid and non-grounded fly may limit the amount of charge to be transferred. As is seen with static electricity. The capacitance of even a man is relatively small, therefore a man can receive a spark with quite high tension but due to very small transferred charge suffer little harm.

    In any fluid charged with static electricity, the charges would drift near surface. (In an insulating solid, charge carriers might be trapped in the interior). They would therefore still be available to shock the fly. Yet if the fluid is a poorly conductive one, the fly would be grounded to a small piece of surface where it lands, and it would take time for charges in the rest of the surface to drift there.

    The fly itself, being an electrolyte aqueous based being, is a relatively good conductor.
