Question

In an electrical circuit...

H = W = (i x i) x R x t   [ H directly proportional to R ]

H = W =  (V x V) x t /R .  [ H inversely proportional to R ]

So is Heat Generated directly proportional or inversely proportional to the resistance in the circuit ??

Joshi sir comment

H = W = (i x i) x R x t   [ H directly proportional to R ]

this one is correct for the heat generated

But i2Rt can also be written as (V/R) x (V/R) x R x t  =  V2/Rt...

therefore my question is how can heat be both directly and inversely proportional to the resistance in the circiut ??
