	This is basic electricity, rather than Tesla specific.
	
	First:
	The current behaves differently from the voltage.
	The secondary inductance blocks/reduces/limits
	current to earth.  This causes voltage to rise
	at the top.	(can be phrased differently)
	To some extent the mag field causes the
	voltage to appear at the top (non rigorous
	phrasing.)

	Neither.  Again, this is basic electricity, rather
	than Tesla coil specific.  Excess electrons (pushed
	out there by the primary field) will try to flow
	both ways (they flow away from each other)

	Neither of which strongly affects electrons,
	however, to stay with the analogy, which may be
	useful.

	Indeed.  The voltage on the top terminal rises and

	falls.  Current does leave the base of the coil.
	However this takes time.
	
	For the case where breakout occurs: consider the pipe
	instead of a cap, it has a balloon.  Push it HARD
	enough and the balloon bursts.
