Hai , iam building a AC dimmer circuit using Triac, When going through all the available circuits online, iam confused between 2 forms..
In some of the Circuit, the input AC Line is fed to Main terminal 2 of the Triac and in some other circuits Load is connected to main terminal 2 and Ac line is connected to terminal 1.
Both circuits have the opto triac between A2 and G, in so far, they are connecting the triac in the same way. Circuit 2 has an additional filter suppressing fast pulses that might trigger the opto triac.

Oh,, i guess iam missing some knowledge here, Iam new to Triacs and analog circuit. But what confused me is in the diagrams above in the first one Load is connected to top part and input line is connected to bottom,, but in the next circuit it is vice versa.
I see, I didn't pay attention to this point. It doesn't actually matter with an isolated trigger circuit. Triac is a bidirectional switch, either A1 or A2 can be connected to the input side.

Yeah i read the same thing.. But i was learning more about triacs and somewhere i read that the order we choose plays a big role, And that the firing has to come from source connected to terminal 2.
is there something like that ?
