Coral snakes are elapids just like cobras. They have a different type of venom than viperidae (rattlesnakes, moccasins and copperheads) although it is still a lethal concotion of protiens. I'm not sure how it would react to a good dose of current. I'm not really familiar with the western species (Arizona coral snake) but the eastern coral is extraordinarily difficult to find. In fact, of all my years hunting snakes, I have only seen one in the wild and it was a roadkill. Considering the uncommon nature of human/coral snake interaction, the fact that a full grown adult is very small compared to most species, and the fact that they have short, fixed fangs and therefore have to chew the venom into the victim, I would say the likelihood of being bitten by one is about as likely as winning the lottery while being struck by lightning during a full solar eclipse while watching the aurora boriealis in Hawaii on February 29th. Just kidding. It is highly unlikely that someone would get bitten by one unless they actually pick one up or stick their hand somewhere it doesn't belong. I think the most likely way to find out about elapids are to find someone in a country where they are prevalent or ask someone at the zoo to let one bite them so you can hit them with a stun gun. I'm sure the likelyhood of that is pretty slim too. If you find out though, I would love to know.
