H= (V²/R)t Going by #1, heat is directly proportional to the resistance whereas going by #2 heat is inversely proportional to resistance. WebDerivation for the equation of heat generated in a circuit, Joule's law of Heating P = I^2 R P = I 2R Consider a circuit as shown in the diagram, with a potential source (battery) of V V volts driving a current I I around a circuit and across a resistor of resistance R R.
WebHeat is defined as the sum of kinetic energy contained by the molecules of that object. The SI unit of heat is Joules. In c.g.s system it is measured calorie. 1calorie= 4.2joules. Heat depends on mass of the object and average kinetic energy of the molecules. Heat is directly proportional to the mass of object and average kinetic energy. WebWe can calculate the heat released or absorbed using the specific heat capacity \text C C , the mass of the substance \text m m , and the change in temperature \Delta \text T ΔT in the equation: \text q = \text {m} \times \text C \times \Delta \text T q = m × C × ΔT Heat in thermodynamics
