However, I've seen "earth ground" conductive stakes driven into the ground in order for electricity to be grounded, because it will find its way down there. However, it never made sense to me why earth would even provide such an effect: why electricity would ... WebNo, ice is not capable of conducting electricity. With no free-charged ions present, there is no passage of electric current in ice. When water crystallizes into ice, it causes poor ionic mobility with a high resistivity level. Any element that can conduct electricity must contain ions, which are small, mobile, charged particles.
