hello folks,
Actually I'm not an engineer, but i have a couple of questions regarding electricity and i hope i am posting this in the right forum :)
1- when there's a charged object, that comes close to another object, a spark tends to happen between them, so that the charged body emptys the charge it holds.
My questions is: what is the rule that governs the amount of charge required to generate this spark in respect to the distance between the 2 objects?
2-I was looking for objects with high Relative permittivity and found a table on wikipedia telling that there are objects with an ε over 200,000. does this mean that, these objects cannot hold any charge practically?
thanks guys :)
