ωτ∫

Lets say the swich is moved to #2 position instead of #1.
I cannot figure out what is happening with the current in this RC circuit. Im guessing current would start from VS to R3 then to R2.

Re: ωτ∫

Actually, when you flip the switch from 1 to 2 the current isn't flowing through Vs anymore.

Re: ωτ∫

Based on electron flow (neg to pos) current is flowing.

It may be flowing, but when the switch is on 2, it is not flowing through Vs.

Re: ωτ∫

Ok thats true. I think the idea is that once switched to #2, Vs is shut off. What time is taken to discharge the capacitor? I guessing just the t=RV formula could be used.
