Okay- first off, I know enough science to sound like an idiot, so please be gentle :-) Now, IF you had a dragon that generated an electrical charge, it wouldn't be able to direct it, lightning-style, without being able to generate an opposite charge at it's target- right? So in essence, to shot a bolt of lightning, the dragon would have to create a charge in the ground or on it's target, and charge itself at the same time- right? If the above is right, then would a target, particularly a person, sitting on a rubber or EPDM sheet, be immune to this discharge? Or alternatively, would the target be best to hide in a Faraday Cage? This is all for a post-apocalypse sci-fantasy sort of thing, so I don't mind rewriting some rules of physics, but not outrageously so. Thank you so much in advance!
