	Why?
	I fail to see why resistance should cause a bump.

	(is something else, say a synchronous switch of any sort, were
	adding energy synchronously, a bump might be seen.
	
	If an asynchronous switch of any sort were doing so, the
	'bump' would 'wander around' from cycle to cycle and be
	invisible, unless single sweep/storage/digitizing scope
	were used....)

	Not if the 'scope is any good.
