A battery is not a source of charge. It creates potential difference and is capable of separating charge, but the battery terminals are uncharged (almost). Also, charges do spread over the surface of insulators as well.

@NickKidman I can try, but it really seems like you're in a better position to write an answer like that :P

comment Exactly how much lift is needed to overcome the weight of an average person?
@User58220 The kilogram. In the case of the fps system, as I was taught, pound is a unit of force (weight) and there is no corresponding fps mass unit

@Dilaton yes. Try to improve the question up to plicy before flagging, though.

@User58220 My bad, you're correct, the pound is a unit of mass. Strange; I was explicitly taught that the pound was a unit of weight and not mass.

@User58220 Nope. Pound is a unit of weight, kilogram is a unit of mass. The metric system's corresponding unit of weight is kilogram-force, though you can of course use Newton.
