according to the formula H=i²Rt for the heat produced in a conductor due to the flow of current through it, HαR whereas according to the formula H=v²t/R,Hα1/R where the symbols have their usual meaning, explain the apparent contradiction

Answer:
Explanation:
According to Joule's law of heating,
H= I^2Rt-----------☆
According to Ohm's law,
V= IR
V/R=I-----------------◇
Substitute I=V/R in ☆
H= (V/R)^2×R×t
H= V^2/R^2×R×t
H= (V^2/R)×t----------♡
In ☆, R(Resistance) is directly proportional to the heat produced and in ♡, R us inversely proportional to the heat produced.
