WebAug 2, 2024 · Solution. We can use heat = mc Δ T to determine the amount of heat, but first we need to determine Δ T. Because the final temperature of the iron is 73.3°C and the initial temperature is 25.0°C, Δ T is as follows: ΔT = Tfinal − Tinitial = 73.3°C − 25.0°C = 48.3°C.

So if we take a very short time d t the energy in that time is: d E = V I d t. Now, in our system (the spark) both the voltage and current are functions of time, so to calculate the total energy we need to integrate V I d t: E = ∫ V ( t) I ( t) d t. And that's how we calculate the total energy in the spark.
