Help with "damage modifiers"

I don't know if this question is on the right area of the forum so I'm sorry if I made a mistake.

I'm kind confused with how damage modifiers work on Path of Exile 2 so I will make some question:


1 - Let's say I have a attack that deals 100 physical damage and 20 Fire damage, on my passive tree I have 10% extra physical damage and 20% increased attack damage how this work? The "10% extra physical damage" increases the weapon damage? And about the increased attack damage? it increased the total damage of the attack? Including elemental damage? (before or after "more damage" modifies)?

2 - Now the second question how "... as extra damage" work? Let's use as example the "Essence of Storm" from the monk starting point, it say "gain 5% of damage as extra lightning damage" what exactly is " of damage"? It's all the physical, elemental and chaos damage from the weapon? And this extra damage can be converted? ( With Painter Servant for example).


Sorry if this is hard to read english ins't my main language.

Maybe this will help.
