Web26 de feb. de 2024 · Assuming that all the electrical work is converted into heat energy, then \[W=H\] Here, \[H\] is the heat produced in the circuit. \[\therefore H={{I}^{2}}Rt\,joules\] This relation is called the Joules Law of Heating. Note: Using relationships from ohm’s law, the derived formula for heat energy can also be written as- WebThe efficiency of a heat engine is given by ղ = 1 – Q 2 /Q 1 Q 2 = heat rejected to the sink Q 1 = heat absorbed from the source The efficiency of the heat engine will be 100% only when the temperature Q 2 is 0. This cannot happen because if Q 2 is zero, the temperature of the working substance will go on increasing. At a certain stage, the temperature of the …
