What role do R2 and C1 play in dampening the IG1 current supply?

Okay, I've re-tooled my question.

What role do R2 and C1 play in dampening a sine wave on the current supply IG1 in the following circuit?

I want to understand the fundamental theory behind this.

What are your thoughts so far?

cuz its a simple RC circuit. that's why. the changing current that the cap pulls induces a "compensating" voltage drop in R2.
