Question
In an electrical circuit...
H = W = i2Rt [ H directly proportional to R ]
But i2Rt can also be written as (V/R) x (V/R) x R x t = V2t/R...
H = W = V2t/R . [ H inversely proportional to R ]
therefore my question is how can heat be both directly and inversely proportional to the resistance in the circuit??
Joshi sir comment
you should take the formula in which one variable is constant and for a circuit current will be constant

do not go on formula use common sense if more resistance then there will be more heat production
