According to joule's law of heating, H=VIT,on applying Ohm's law, we get H=I^2RT.....so heat is directly proportional to resistance.......however if we substitute I=V/R(from Ohm's law), we get H=V^2T/R,that is heat is inversely proportional to resistance.......how can the same heat be directly and inversely proportional to same resistance by applying the...
