Several basic questions about alternating voltage / current

I have a few straightforward questions about AC but surprisingly can't find any of explicit confirmations. … Is it animated version of AC which demonstrate propagation of alternating voltage (and current) waves from AC generator (assume it connected on left side) toward load? …

A few basic questions about simple electric circuits

First I would like to describe how I understand processes in DC circuit, and then ask question about AC which cause confusion. … I mean if I measure current in AC circuit or look at graph for example of AC RC circuit where current curve lead voltage by 90 degrees, it always related to "main" current, and not these charging / discharging …
