Heat Transfer in Electrical Circuits

Click For Summary
SUMMARY

Heat transfer in electrical circuits occurs when current flows through a resistance, resulting in heat production. This heat is transformed into internal energy within the body, increasing its temperature according to the formula mc(dT). In a steady state, heat flows out of the body, adhering to the conservation of energy principle. Ultimately, heat serves as the final waste product of all other energy forms in the circuit.

In an electrical circuit, when current flows through a resistance, heat is produced. Is there some quantity (?) into which heat is transformed when it flows through a substance (all substances having some resistance to heat flow)?
 
Science news on Phys.org
All the heat that flows in a body simply flows out the body, as a result of conservation of energy around your control volume if it is steady state. Otherwise, the internal energy of the body increases as the temperature of the body rises from mc(dT).
 
Heat is the final waste product of all other forms of energy.
