if a bulb is connected in series with two bulbs parallels to each other which formula should I useto find which is more bright? why can't I use heat directly proportional to power and the relation of power in series and parallel? How do I know which relation to use in a question because heat is directly proportional to resistance in one formula and inversely proportional to it in other?

Is the power in series and parallel different for other appliances like when we connect bulbs in series we take it inversely proportional to resistance but for others we take it directly proportional?

The correct relation between heat produced (H) and electric current (I) is?

Q. The correct relation between heat produced (H) and electric current is
H is proportional to I
H is inversely proportional to I
H is proportional to I²
H is inversely proportional to. I²

V=IR, from this equation it's clear that V is directly proportional to I and R..
I=V/R, from this equation it's clear that I is directly proportional to V and inversely proportional to R.
But when V is directly proportional to R and I is directly proportional to V then why is I not directly proportional to R?
