Heat Transfer in Electrical Circuits

AI Thread Summary
In an electrical circuit, current flowing through resistance generates heat, which is a transformation of energy. When heat flows through a substance, it is influenced by the substance's resistance to heat transfer. In a steady state, heat that enters a body eventually flows out, adhering to the conservation of energy principle. If the system is not in steady state, the internal energy of the body increases, resulting in a temperature rise described by the equation mc(dT). Ultimately, heat is considered the final waste product of all other energy forms.

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.
 

Thread 'Condensate rate of water for an air conditioning cooling coil'

I need to calculate the amount of water condensed from a DX cooling coil per hour given the size of the expansion coil (the total condensing surface area), the incoming air temperature, the amount of air flow from the fan, the BTU capacity of the compressor and the incoming air humidity. There are lots of condenser calculators around but they all need the air flow and incoming and outgoing humidity and then give a total volume of condensed water but I need more than that. The size of the...

Thread 'Entropy and configurations of microstates'

I was watching a Khan Academy video on entropy called: Reconciling thermodynamic and state definitions of entropy. So in the video it says: Let's say I have a container. And in that container, I have gas particles and they're bouncing around like gas particles tend to do, creating some pressure on the container of a certain volume. And let's say I have n particles. Now, each of these particles could be in x different states. Now, if each of them can be in x different states, how many total...

Thread 'Why work is PdV and not (P+dP)dV in an isothermal process?'

Let's say we have a cylinder of volume V1 with a frictionless movable piston and some gas trapped inside with pressure P1 and temperature T1. On top of the piston lay some small pebbles that add weight and essentially create the pressure P1. Also the system is inside a reservoir of water that keeps its temperature constant at T1. The system is in equilibrium at V1, P1, T1. Now let's say i put another very small pebble on top of the piston (0,00001kg) and after some seconds the system...
