Question

Basically , H=I²Rt in which H is inversely proportional R bt as per calculation of we calculate , since I=V/R so H= V²/R²*Rt , therefore which gives us H=V²/R*t in which H is inversely proportional to 1/R but it contradicts the previous one...so which can be considedred as right ?

Answer 1

$in \: \: \: \: h= i {}^{2} rt$
Resistance is directly proportional to the heat
this because here current flowing through the resistor is constant.

but in statement where

$h = v {}^{2} \div rt$

here resistance is inversely proportional to the
heat because voltage across the wire is constant.
